I always wondered about brakes and braking distance - a lot of

Most brakes can bring the wheels to a complete stop instantly if you push your foot all the way down. The problem is the tire then skids across the pavement because the momentum of the vehicle overcomes the friction between tire and road. Have you never seen skidmarks in a movie or safe driving PSA? Are you actually retarded?

lmao this started off so nice and constructive

>>17646120
ive seen skid marks, but are you saying there's no way to just sort of cancel or delete the momentum of the car

>>17646120
This. The brakes can bring the tires to a complete stop just fine. The issue is that the Earth is rotating and the car slides across it.

Almost all brakes can stop the wheels immediately, its the tires that can't hold the frictional forces being imposed on them.

>>17646129
Nope not unless you find way to violate physical laws.

>>17646126
It literally is a retarded question.

>there's no way to just sort of cancel or delete the momentum of the car
Absolutely there is. Just mount a cannon that fires forward with enough power to cancel out your momentum.

This will absolutely make you the safest thing on the road. Guaranteed.

>>17646129
just rig your tail anchors to deploy under hard braking.,,.its 2017 I thought everyone did this

>>17646110
>Why hasn't anyone made a brake that immediately stops the car?
It's called a wall, and if you hit it, it will fuck you up.

>>17646110
There's static and kinetic friction.
Have you ever had to push something really heavy across the floor, like a refrigerator? If you noticed, it's easier to keep the refrigerator moving than it is to get it moving, this is because kinetic friction is weaker than static friction.
So when you hit the brakes on a car, there is kinetic friction between the pads and the rotors because you want all the friction you can get between the tires and pavement

Because driver would look like pic related after breaking

immediate stop = infinite g-forces

There's ways to improve it certainly. The C7 has a 60mph stopping distance of 90 feet, almost half the average. The type of tires you use play a huge part, plenty of brakes are capable of applying the necessary stopping force but few tires can take the friction. A good set of racing slicks can stop way faster than your average cheap all seasons.

Earth's rotation plays little to no effect here...

>>17646433
I imagine some 355 wide slicks with some 12 piston brakes would do the trick.
