Safety & Defensive Driving Course

On 18th July 2008 (Saturday), we joined the Safety & Defensive Driving Course organized by Autoworld. It was a good and fun session. Below are some information and story if you like to "read".

Our Rally-X Hero In Action

Theory Session:
Basically, this session is more on awareness, usual mistakes or problems (especially with Malaysian drivers). It's an informative and good session, though, I believe many would agree that more time should be spend on the practical session.

We're also taught about push-pull steering and it's benefit compared to hand-over-hand (which most of us usually do; our hands will cross the steering). One main reason is the for cars equipped with Air Bags, if it were to deploy, the impact is enough to break our arm and consequently smash onto our face.

For those who doesn't like to wear seat belts were also explain of the possibility why, such as, uncomfortable. This is all mainly due to wrong seating position and adjusting the seat belt wrongly. The seat belt should be adjust so it's rest on the shoulder and the waist.

Practical Session:

1. Basic Check On Cars

2. Slalom Test
I can't really recall the actual purpose of this session. Basically, we're taught the correct seating position, and push-pull steering demonstration. We were shown some demonstration by the trainers, although it might look "not really fast" but in fact it's not as easy as it looks, if you look closely at the driver, you'll see he/she will be very busy steering the car. Later we also sat in one of the cars and experience it while being explain how we should do it via push-pull steering technique.

Another catch to this slalom test is, you should maintain your speed throughout the slalom; which means, if you enter at speed of 30km/h, you should maintain your rev and slalom through the course at 30km/h till the end.
It's not easy, you'll see most of the participants doesn't maintain the speed.

3. Understeer
This session we get to experience understeer (wheels locked) session, where to overcome such situation for cars without ABS, we need to do cadence braking (that is to pump the brakes) to allow the car to steer. For session onwards, most of the participants used the 5 Honda sponsored cars, with only the Honda City's ABS turned off.

4. Oversteer
This is the most fun session I must say! As we enter the area, we need to turn the steering to the left and the trainer will pull the handbrake causing the car to oversteer. At this point, we need to countersteer quickly. To overcome the oversteer, we need to ease-off (not sudden let go) and absolutely NO Braking! (Braking will make the car spin out) steer to the direction we want to go. Failure will cause too much oversteer or spin out. We can also play a little bit with the throttle to "straigthen" the car back to where we want to go.

This session can be very dangerous and it's strongly adviced to have a trainer with you in the car. Each participants get about 3 chances, which I personally find it not enough because I think most of us still panic and revert to 'AUTOPILOT' instinct. We haven't get used to the feeling of oversteer, stay clam and steer or do the 'right' thing.

My first time was shocking to me when it oversteer, I got panic and applied some brakes; The trainer immediately notice and 'scolded me' (hehe), "Why did you press brake???"
Oooops, luckily it didn't spin and still able to "pass", hehe
The 2nd round, I think a little too much oversteer and come to a halt, sort of, but still able to "pass" through the gate (I think). The trainer also notice my mistake and tell me to countersteer earlier.
The 3rd round, I feel quite messy too cause there's many left and right and I use the throttle to straighten the car. Heard the walkie-takie someone say something like "Nice one", but the trainer replied "He already step on the gas". Ooopps? =P
This trainer is very observant and good I would say, he's able to observe what I've done clearly and also to correct mistakes/technique/problems =)

CHALLENGE
There's a special challenge organize for us, a short mini autokhana session with the Honda Jazz. I was the first one, oh dang. I think most of us loose the time at the reverse parking session; For those more aggressive and take the risk, score a good time. The first being blackdolphin, I think around 26seconds++, which his time was unbeaten for some time, until another Honda driver score around 25 seconds++. Some aggressive one scored good time too but they either touch/hit a cone or two. Each cone give 5 seconds penalty.

WRC 206 in Malaysia - Totalled!

Ever wonder who got the WRC 206 car registration no.? Well here it is .. the only 206 in Malaysia with the plate no. of WRC206.. and its a TOTAL LOST.

The no. was bought by the car owner for his Peugeot 206 (Not Bestari ver.) and the car lost control at some corner near Seremban? (according to source)

It's actually an old model 206

What a pity... WRC 206..

Anyway the good thing is, the driver came out of it without any scratches. And he kept praising how good and safe this car was. And btw he is not selling the WRC206 plate no. haha.. maybe he is going to get another 206?...

WRC206 - on a Peugeot 206 (Quick silver) status =Totalled.
WRC308 - on a Peugeot 308GT (Red) status = Test drive car. (Nasim)
WRC407 - on a Peugeot 407 (??) status = ??

Thanks to BlackDolphin for the pictures and information.

Spotted! Malaysia Patrol car using 206... nice..

Understanding ABS (Anti-Lock Braking System)

Have you ever encounter a situation where:

1. You met an "emergency" situation

2. You slammed the brakes and turn your steering to avoid the obstacle(s) ahead.

3. BUT... your car just won't turn! It's still going straight even tough you have turned your steering.

(From the outside, you will see your wheels actually already turned, but why does it still going straight?)

So, why does your car never response to your steering input? You already turn your steering and the wheels already turn, logically, it should turn, but why doesn't it turn and still going straight?

This is because your wheels are locked.

Some definition found about wheels lock:

"When wheels lock, they no longer have traction with the road and in turn cannot steer/stop a car efficiently."

"When wheels lock, the vehicle can no longer react to the driver's steering because the lock wheels can no longer convey the optimum braking power and necessary turning force to the street."

This is where ABS (Anti-lock Braking System) comes in; It is actually a SAFETY FEATURE meant to help preventing situations like the above, wheels locking and allows you to maintain steering (remains steerable, stable, while fully applying the brakes)

Do not mistaken or neglect this FEATURE as some fancy feature to show off; It is a SAFETY FEATURE meant to help prevent or minimize the problems resulted from wheels locking and also drivers in panic situations especially situations where human reflex conquers all (yes, even profesional drivers (racers, rally drivers) makes mistakes or looses their conscious/control, there's nothing to be shy about).

Explanation of ABS:

Without being too technical, ABS is basically a system of a computer and sensors monitoring the speed of each wheel. When you press down on the pedal, the system kicks in and it takes over how each wheel should slow down to prevent unnecessary skids. 

In short, ABS prevents wheel(s) locking when applying full brakes and promotes Steerability and Stability with the shortest possible braking distance.

The feeling when ABS kicks in:

When you slammed the brake and the ABS kicks in, you will feel occasional pulsing of the brake pedal; Do NOT panic or be afraid especially if you are not used to vehicles with ABS, just brake firmly and allow it to do its job.

If you're going pretty fast and brakes firmly on the straights, you might actually feel/experience your car "straightens" itself during the course of ABS function; Hence, you can guess what will happen if your car is without the ABS.

How to apply the brakes in a vehicle with ABS:

Should I pump the brake pedal when stopping in slippery conditions?

You absolutely should not pump the brake pedal in a car with ABS. Pumping the brakes is a technique that is sometimes used in slippery conditions to allow the wheels to unlock so that the vehicle stays somewhat straight during a stop. In a car with ABS the wheels should never lock in the first place, so pumping the brakes will just make you take longer to stop.

In an emergency stop in a car with ABS, you should apply the brake pedal firmly and hold it while the ABS does all the work. You will feel a pulsing in the pedal that may be quite violent, but this is normal so don't let off the brake.

Advantages or Key Features of ABS:

1. Prevents wheel(s) locking.

2. Shorten braking distance.

3. Ensures the vehicles remains steerable and stable.

Something you should know too:

However, this isn’t a foolproof system that would guarantee that skids won’t ever happen. Definitely, you have to consider other factors like the condition and grip of your tires. The road surface will also be a factor. Oil and tar on the blacktop will definitely give you less grip than a paved concrete road. Your speed and direction would also play a factor. The ABS doesn’t necessarily shorten the stopping distance of your car too.

So then, what's so good about it? Well, nothing is perfect. Remember, this is a SAFETY FEATURE designed to HELP prevent situations like wheel(s) locking mentioned above.

So what about those "MANUAL" ABS I heard about?

These are the "technique" when ABS wasn't available or you can call it "simulated" ABS. Have you ever heard about let off the brakes and re-apply again (or pumping the brakes)? If yes, this is the theory/technique; you release the brakes and re-apply to prevent the wheels from locking.

As many people are crazy about Initial D anime, which talks about the main character Takumi with his "manual" ABS; don't be too over-confident or "carried away" with "manual" ABS just because some anime shows off about it.

First of all, it's an anime, secondly, we're driving on the streets not tracks, and finally, we're all humans; we makes mistakes and in panic situation, sometimes, your reflex overwhelms and the "mean time between accident" is just too short for you to react in time. (don't be afraid or shy to admit, even profesionally race car drivers makes mistakes or overhwhelm by such situations)

Also, don't forget ABS works much much faster and efficient than a human, it can monitor the wheels, speed and also apply and release braking pressure up to 20 times in 1 second; It is supposed to be a SAFETY FEATURE to help the driver.

Manual ABS are useful when your car doesn't have ABS, and it often is an important technique for the driver; but don't be mistaken that one can master this technique and think they can prevent all the situations mentioned above.

Don't "play a fool" with your life and others.

Additional Information about "MANUAL" ABS:

Recently, I was told about another definition for "MANUAL" ABS - Aku Brake Sendiri. (It's a Malay word which means "I Brake Myself". Coincidence huh?

What about ESP (Electronic Stability Control) or TCS (Traction Control System) or those "techie" SAFETY FEATURE?

Well, those are more advanced SAFETY FEATURE, which consist of ABS (or includes ABS). It provides further traction control by making use of ABS and few other SAFETY FEATURES.

It can be another topic, so we will not "write" about it here.
