***worst Traffic Violation Thread***

I'm going to take it as a good thing that I am not into the finer points of mind altering chemical substance use.

One of my clients is a dentist. N2O is very safe stuff, if used properly, of course. It's not really in the same league as the more popular chemical substances.

Unless one wants to get into a morality argument centered around ethical hedonism rather than a discussion on legal basis.

*gasp* god forbid we discuss ethics!

Would not logic demand that a vehicles stopping distance should determine that max. safe speed, and not an arbitrary number. Why is the speed limit the same for a 1978 Chevy K1500 fitted with poor tires and a 2004 AWD Porsche fitted with good high performance tires?

...which is why speed limits are made on the safe side giving consideration to the worst of vehicles in the worst portions of the road, and maybe even lowering it a bit for more safety. but that leaves a margin of safety for most cars, which is why most people speed by 5-15 MPH.

Actually, all vehicles stop in the same distance.

boy you're good at using google. However, you failed to realize that in Lohman's argument he described two cars, one with good tires, one with worse tires. The greek symbol Mu, in the denominator of that fraction, is the coefficient of friction between the tires and the road, which has a profound effect on stopping distance. Furthermore, that formula is elementary and flawed, it omits any account for the friction between the brake pads and rotors. Unless, of course, you believe that brakes don't matter. So thaaaats why people spend an extra $6k on their porsches for ceramic 6 piston brakes....because they do nothing?

Guess what: Until you elect someone who puts raising school zone speed limits in your area on their list of priorities, you're opinion of what's "reasonable" doesn't mean squat.

Here it's 30kph/18mph.

But you didn't read what I said. I said in CA the speed limit IS 25 mph and that works just fine.

And Lohmann: yes, I';m sure it's not my story. I am not a man, nor do I stop strange drunk men in order to attempt to rescue babies. And my boyfriend is in CA. The last person who ran me over with a car was my mother.

So no: it's not me .

Stopping distances aren't the only factor in safe road speeds/geometry.

You also need to take into account the stopping sight distance (which also takes into account reaction time).

All designs are based upon a representative vehicle including driver eye level, reaction time, headlight elevation.

If we were to remove all speed limit postings, you would find that most drivers would not significantly increase their speed.

But brake don't mean anything. At least not if you're going to consider worst case scenario driving. Stopping distances in those formulas are for LOCKED wheels.

Good brakes are all about being able to lock your wheels, being controllable, and remaining consistent with extended use.

The better brakes will improve the reaction time. But not the stopping distance once the wheels lock.

Now if the whiners who don't like the tickets they got in a school zone can show me their racing permit and the top notch car they're driving, perhaps you might want to take this pointless exercise further. Otherwise, the tangent is just a game to try and prove yourself right.

I did two university semesters on vehicle dynamics. I know there are differences. But explaining them or getting into semantics is pointless in a thread that will be dominated by a pissing contest of "I can drive better than that".

Tropical_fishy: You could read better as well. My position is not to advocate any "right" speed. Only to point out that there are reasons behind the posted limits. Your area may have decided that your speeds are safe enough. The area the whiners live in haven't. If you get done for driving 45 in a 25, I have no more sympathy for you than the person done for 25 in a 15. Fight to have the limits changed if you want, but don't cry when you get busted for not following them.

and youre disregarding the fact that many cars have anti-lock breaking systems?

But better brakes will lock quicker - and you live far enough north to know that a tire sliding does not always mean traction - locked brakes are not all that. I don't buy that mass has nothing to do with the inertia of a vehicle either...

Beyond that different tires will get different traction, changing the friction of the formula.

As to this portion

Now if the whiners who don't like the tickets they got in a school zone can show me their racing permit and the top notch car they're driving, perhaps you might want to take this pointless exercise further. Otherwise, the tangent is just a game to try and prove yourself right.

Why post on a message board at all if it is not about the discussion of ideas, concepts, and theories?

well im the whiner that got the ticket (really I didnt get a tickit for it). but im not whining about it, its just how many people have been pulled over for speeding doing 25mph.

but to get back on topic SlartyBartFast, whats your top violation ?

On the way home from a paintball tournament, we got a ticket in every single county on the way home, totalled up to 7

7 tickets in a day...? what, did the driver keep switching so you'd each take one for the team, or did someone get their licence revoked?

I'm no saint. But I don't have anything to brag about. Nor do I have reason to complain about the time(s) I've been caught.

However, I've already posted elsewhere on AO my worst car related near-death experience.
1976 Austin Mini, ~120kph, 45 deg into a highway barrier. At the end of it all, car was 2 feet shorter and a half foot narrower over the whole length...

Time DOES slow down. Or, your perception of time/events speeds up...
