There is no difference between winter driving and summer driving, except for one:

The coefficient of friction.

Every behaviour your car exhibits in the snow (fish-tailing, under-steering, etc...) will happen on dry roads if your car has sufficient horsepower, and you're going fast enough.

@Ricardus

Well, remember there are TWO coefficients of friction, static and dynamic. The dynamic is much lower on wet ice, so recovery from a skid become a different exercise than on dry pavement.

@Professor_Stevens yeah, ice is a different beast altogether. I should have clarified that.

Heh. Don't pay any attention to me. I'm that physics dick who always stands up in the theater during the rebels' run on the Death Star and shouts, "But there's no sound in a vacuum!"

We are the worst kind of dick.

@Professor_Stevens oh I'm right there with you. But as I said in my post it was for snow. Most science fiction shows don't get the physics of space flight correct either. Imagine if you were driving a hovercraft. That's a better example in two dimensions of how space works in three.

@Ricardus

Yeah, proper physics would confuse people, all the more so after a lifetime of seeing it misrepresented in movies and TV. "The Expanse" came closest, though the magnetic boots were almost comedic, they were so retro and silly.

@Professor_Stevens I need to finish watching the expanse and I have access to it so I have no excuse. Yeah their science was the best.

@Ricardus

I liked it. Some of the loose ends stayed loose, which always means a sequel is possible. But, the more time that passes, the less likely it is you'll get the same actors, and I thought that particular cast was excellent.
