Well - if you look at the average speeds on a typical urban US highway, even a snail would overtake the commuters.

You've...never...actually driven here, have you?

The DC Beltway is insane; the speed limit is 55 mph but if you're going slower than 65 you're catching a lot of hate from other drivers.

Usual scenario is going 75 mph bumper-to-bumper.

And if you hop on Interstate 95 to Baltimore everyone's doing like 80.

True that during rush hour certain stretches of certain roads turn into a parking lot, especially I-95 southbound towards Richmond. But when it moves, it moves, uncomfortably so.

I make an effort to sleep not far from where I work in order to avoid that craziness, but I know people who live as far away as West Virginia and drive to the DC area every day, which is crazy!

All that speeding is illegal, of course, but the speed limits in the US are really just de facto revenue collection schemes for governments, with many speed limit zones painfully low-balled. When it's time to drum up more money the cops can just go pick out the worst offenders and write more tickets. Our Interstates are actually built for high speeds, for the most part.

And I might add, I've spent enough time on the West Coast to know that the Los Angeles freeway system is even scarier, in terms of high-density high-speed traffic. You have to adjust your comfort level.

On the other hand I've been to a lot of countries where the idea of traffic rules seems to be nonexistent, at least in the US we do stop at red lights and so forth...

On the I-75 corridor from Chattanooga to Atlanta it's not out of the routine to break 100 mph, and that's mainly to avoid being run over. I've gone faster, but I was never in the lead.

Yeah, I've heard Atlanta is crazy. I've only driven past it once or twice a long time ago, never spent any time there.

I-4 across Florida is probably the American version of the autobahn (that I've been in, anyway).

Also, there is no real reason to set a speed limit

Mhm, I wouldn't agree with that. First it'd be much more eco-friendly to just do 120 like the Swiss. So from that perspective it definitely makes a difference.

And having driven from Füssen to Hamburg and from Quimper to Strasbourg I can say a speed limit is much easier to drive. In France you put your cruise control in and for the next few hours it's easy. In Germany you want to drive 130 or 140, then you have to overtake something but can't because some guys drive with 160 or 180 on the left lane. In France the most I encountered was some guy doing 150. And even if you go out in front of them they are relatively okay, slow down, wait for you to overtake and keep on going while in Germany...lights flashing, lights flashing, turn signal on, CAN IT IDIOT, WE'RE ALREADY DOING 150 YOU !

So I'd be okay with something like Poland, 140 km/h speed limit.

I've driven across the US from coast to coast a few times. Out in the middle of the continent there are stretches of highway where you can set your cruise control on 80 or 85 mph and just relax and enjoy the scenery for hours. Mainly on Interstate 40 through the Southwest, and I-70 in Utah after going through the Colorado Rockies. That Utah drive is one of the true pleasures I've experienced driving, coming down from Grand Junction up in the mountains and cruising downhill onto the vast wide open desert, with mountains miles away to either side, the sun shining bright, and the road so straight and smooth you don't even feel the speed really.

Out west the speed limits are generally higher until you get to California, where the fun stops and there are cops all over the place. Kansas was another state where there were speed traps left and right the entire length of the highway. And once you get east of the Mississippi River you have to readjust to driving slower, which is tough after being in the wide-open for days.

Closest thing I've ever encountered would be I-10 past Palm Springs. Hit 95 at points over Christmas break, and I was STILL being passed.

I have only seen that the difference between rush-hour and Sunday morning is the speed at which you are bumper to bumper... with average speeds during rush hour of around 10 km/h, what we would call "nothing moves at all" here.

The Situations that you describe seem to be similar to large italian cities, except that the Italians seem to be a people that navigate by hearing only... :lol:

In Canada, the speed limit on the highways is 100 km/h and it is quite respected. You can drive at 110 or 115, but starting from 120, you risk to have a ticket. I feel bad reading your comments...

That's not how IQ works. Reading stuff won't make it harder for me to figure out stuff like this:

It might if the stress of people saying dumb things on television gives you an aneurysm. Or I can come up with some other convoluted excuse to justify my absurd claim.

Can anybody reccomend a particularly good tutorial for writing collision physics code?

With or without using stuff like PhysX?

Not sure. Does PhysX require control of the event loop like Box2D would? I already have an existing event loop that updates things like gravity, and I just want to have the collision detection work its magic each frame after the other updates happen, ie

Code:
while(weAintDone())
{   for(AlltheTHINGS)
{  thing.update();
// iterate through all of the things and update
// them with regards to gravity forces and other forces
// (rocket engines, air drag, etc.)
}
for(AlltheTHINGS)
{   // check if a collision is happening and do stuff to make it
// not be colliding anymore
}

}

Originally I wanted to use Box2D, since it sounded like a good fit for the project, but after some discussion with a friend of mine who is helping me with the project, it sounds like that wont work very well since Box2D has its own event loop. (and I cant just work inside Box2D, since its precision is usually only at float, whereas I need long double)
