I’m no expert in cars and how they work, which is definitely why I don’t know the answer to this question. What I don’t get is how cars, even when going down a slope at high speed, can gradually slow down and freeze, even when on a steep slope. Why does it not roll down? I don’t get how the tires freeze the car like glue, like shouldn’t it move slightly at least?
EDIT: I definitely worded this badly lmao. I was more interested in how cars on steep slopes don’t move on slopes, because wouldn’t an object without wheels still slide downwards when on a slope?
EDIT 2: Thanks for answering the question. It makes sense now that the friction of the rubber tires and the material on the road is what keeps it so still when brakes are applied on slopes.

Depends on the friction.
Friction between the ground and an object depends on the weight, and the material of the objects in contact.
Cars are heavy, and cars have rubber wheels which have a high coefficient of friction with the asphalt, so they don’t slide. If there were ice, cars would definitely slide. See 1:53 here:
