I agree with you with one exception: some cars are not powerful enough to do that :) You won’t find them stateside, but in Europe there are plenty of small-engined cars that won’t roll on their own, unless you really know what you’re doing and/or rolling down some incline.

This is how you fix the problem... add some steps up before going down (pictured: RIO): https://www.google.pt/maps/place/Rio…
