PS: For those talking about braking distances and inverse square laws for kinetic energy/stopping distances etc, does that mean if I drive a sports car with superior braking/shorter stopping distances than the average car I should be allowed to drive at a faster speed, as it is just as "safe"????

No, unless you're a superior specimen of the human race and reacts faster than most.

The total stopping distance of a vehicle is made up of 4 components.

* Human Perception Time
* Human Reaction Time
* Vehicle Reaction Time
* Vehicle Braking Capability

in regard to the last, it depends on factors such as;

* the type of braking system,
* brake pad material,
* brake alignment,
* tyre pressures,
* tyre tread and grip,
* vehicle weight,
* suspension system,
* the co-efficient of friction of the road surface,
* wind speed,
* slope of road,
* surface smoothness
* the braking technique applied by the driver.

So while you may be really, really good, others around you are probably not and there are more of us than there are of you. Go crunch the numbers on that one.

As a matter of interest, race cars do not have ABS

reason: total stopping distance of a vehicle is less without them ( in the hands of a skilled driver)

In terms of reaction time, most people are muppets with their mind somewhere else. The typically stated reaction time is 1.5 seconds, but if one is paying attention and prepared it should be about half a second. Easier said than done of course.

Getting slightly back on topic, the aspect which I have an issue with is being booked for speeding when overtaking a slower car on a two lane road. Example, you're doing 100 kph and the car in from is doing 95 kph.

To my way of thinking, assuming the road ahead is clear, it is better to overtake the slower car at say 120-130 kph as there is less time, hence possible danger, hanging out on the right hand side of the road than if you maintained your overtaking speed at 100 kph. Yet I have been booked for applying that concept. Annoyed me no end.

I will have a go then.

1) Age

2) I work on vehicles for a hobby, this has given me a good understanding of dynamics of vehicle engineering & handling, in a way that average MV owners cannot know

3) There was one incident.... I was driving at the speed limit on the Pacific Hwy, (100kmph) it was raining, suddenly hit a large patch of oil, on a sweeping bend, in a front wheel drive car. Coming in the opposite direction was a Mack Semi.

If I had been going 5km faster, or had 1% less concentration or skill, I would have been dead meat.

This made me realise you can die thru no fault of your own.

The only protection against this fate is to develop superior defensive driving skills.

My sis-in-law has been hit 3 times by drivers running red lights

I dont proceed thru a green light till I have checked both directions first.

I maintain the maximum possible spacing from other vehicles

Use the vehicle in front to shield from head ons

there is so many things you can do to maximise defensive driving, too many to list

Looks that not only you have enough reasons, but also you can think and be sensible about skills-odds.

And knowledge that unknown circumstances can adversely affect my chance of survival is main reason the way I drive kind of scared, concentrated and sort of on back foot, which gives me margin of safety on everything including my maximum speed.

Yep

And ABS performs even worse on gravel surfaces, which is why rally cars don’t use it.

I will tell you were ABS is downright lethal

In 4WD off-roading, attempt to to climb a very steep hill, decide it is too steep, so need to reverse back down.

Guess what, ABS wont stop the vehicle running away on a loose surface.

stop by hitting tree

This is especially so if u dont have very low range gears/transfer case

electronic descent control on expensive ones probably good

I also laugh when I see rear torque arm suspension, those things would get wrecked in 5 minutes on rocky washed out tracks I have been on

I totally agree, as part of my defensive driving strategy, I commence my overtaking maneuver from WELL behind the vehicle, ensure vehicle RPM is near max torque range, accelerate hard, and complete the maneuver in the minimum time, often hit 120-130km+

This is so much safer than bunching up behind the car and poking your nose out, as I have time to pull out.

going to the snow this weekend..the cops are sons-of-bitches on that road

Re:I beat a 118kmh ticket

I recently beat a 118kmh ticket in a heavy vehicle at toronto NSW on the f3 i was given some very handy inside information.it took me 10 months to win & toronto police are that upset they fitted me up with an offensive laguage charge upon leaving court.

I have a copy of the standard operating procedures & guidelines so if anyone is interested i will upload the info.it is in a pdf.

my advice is go straight to the rear of your vehicle so you are on the in car video & stay there,be polite & DO NOT ADMIT TO SPEEDING reserve your defence for the court as i did.

if you do any long distance driving get yourself a uhf radio to hear the location of the HWP....tb
