Bummer for track folks. It's easy to get a new set of rubber that has a speed rating higher than what the factory provided; It's a lot more difficult for a layman to flash out a speed limit. It's a shame that less and less companies are producing products that take into account that perhaps the potential buyer might actually know better.

No one is taking these Volvos to the track. Do they even make something that'd be worth tracking anymore?

My new iphone will actually ask me to confirm that I am not driving before unlocking when it thinks I am

This depends on whether you have this setting enabled.

I know, but for me it was on by default.

what does poor people not being able to afford to get speeding tickets have anything to do with this conversation? should the OP not drive his car in the way that he wants to because of the price of speeding tickets? should people in wyoming, with access to long stretches of highway with little traffic, not be able to drive their vehicles in the way they want to because manhattan doesn't have highways and has lots of…

The only reason to go fast is for thrills. Going fast is dangerous to other people, hence: fuck you, go slower. I don't care what situation you pull from your ass to give a counterexample, 99.99% of people driving over the speed limit by more than 10-20 are driving dangerously.

> The only reason to go fast is for thrills.

Or, you know, to get where you're going faster. Driving faster adds up over long distances.

I saw the movie last night :)

I saw it years ago, and it was passed off as a joke, but I think it's incredibly true.

I would be willing to bet money that at least 90% of crashes are caused by at least 1 driver doing something stupid. Using their phone while driving, not adequately looking before changing lanes, ignoring signs or traffic lights, driving drunk, etc. Calling these types of crashes "accidents" lessens the responsibility on the person that caused it. When you're in control of a 2,000+ hunk of steel, there's no room for carelessness.

> But the big problem is the roads and the culture around speed. America doesn't have either of those things, and probably never will. A culture of safety is not a "big problem" IMO. The "big problem" is that a vehicle at 120mph requires an insane stopping distance. On dry asphalt: * 60mph: 172 ft * 120mph: 688 ft [1] http://forensicdynamics.com/stopping-braking-distance-calcul...

Doesn't this stopping distance depend on the car? Said German cars have bigger breaks and bigger tyre surface and have been proven to stop quicker. Top Gear showed this often (Australian trip with the m6, Bentley and gtr) all stopping in less than half the Highway Code distance...)

Yes, it matters enough that you should pretty much ignore any skid calculator without a weight component. Consumer reports even put together a list on which cars have the best "safety performance" that measured things like braking distance; the SUVs rank pretty hilariously

My Ag Science teacher used to say that. (not so much about collisions, but other incidents)

Definitely.

Like, there's no such thing as a gun accident. If someone ever accidentally gets shot, it means someone wasn't following one of the prime rules of gun safety.

I seriously doubt "hundreds of millions of people" regularly go for a lap in the Nordschleife.

Especially given the mechanical wear, motor racing (Even karting) is a rich man's game

You don't have to be rich to drive on a track. Champ Car (formerly Chump) is racing with very inexpensive vehicles. I did a track day with a sub US$5000 car that was still faster than many others. People take rental cars to track days for a total weekend cost of under $500. Drag racing costs next to nothing for a normal car.

Stopping distance does depend on the car, but physics has a bigger influence. The kinetic energy in a car is 1/2mv^2. No matter what car you're in, going twice as fast requires dissipating four times the energy in order to stop.

So, take a sporty car with twice the braking performance of a basic car, and you can go 1.44x as fast as the basic car while still having the same stopping distance.

I have a very light car that I use on the track, with an amazing amount of braking for its weight. Full deceleration happens at 2.5g, that's not pleasant. There are also comfort limits here.

I've always wondered why the government sets speed limits but then doesn't enforce them on manufacturers. You can solve 99% of speed "crime" by making it illegal to sell a car that can break the speed limit.

They hope you will break the speed limit so they can make money, that's why.
