I was responding to the idea in the previous post that it was somehow that tires stop the cars rather than brakes or regenerative braking.
> Brakes don't touch the road, the tire does, so it matters not at all how you apply force to the wheel, from the perspective of the tire-to-road interface it's all the same.
This is not the case. Brakes (or regenerative braking) absorb the energy of motion into heat or stored chemical energy. The tires are not doing the stopping.
> brake pads don't use dynamic friction to stop the car
This is also incorrect. Brake pads are using almost completely dynamic friction to stop the car. From the perspective of the brake bads the tire is moving and from the perspective of the tire the brake pads are moving. There's no static friction involved there.
