because they slide... the snow reduces the friction between the road and the wheels so if the car stopped it could lose control.

How race cars differ from normal cars?

Race cars are usually given strengthened roll cages that protect drivers much better than most of the cars on the road. They also have high temperature resistance brakes to allow the car to stop from high speeds most road cars will never see in their life. Sticky tires to allow all the power to be transmitted to the road and; Lastly they most often come with a large engine that gives out a lot of horsepower and torque to a light heavy duty transmission. most cars on the road drive around with v4s and v6s. Rarely do you see a v8 except in trucks or large suvs. But race cars use v8s, v10s, and even v12s to get their lightweight frames to the speed they need to be to stay in the race.


How do cars use friction to stop?

Who is at fault if you pull out and are hit by a speeding driver that then hits 2 parked cars?

You are if you were pulling out of a driveway or alleyway. If you were at a side road it would depend on who had the right of way. If you had to stop but he didn't, you're at fault. If he had to stop but you didn't or if he ran a stop, then its his fault. The fact that he then hit two other cars is immaterial.
