This may very basic, elementary and possibly dumb question but I have to ask.
Why, when parking uphill, driver should steer tires away from curb? Won't steering toward curb also can stop car by rear wheels? Think about it, the car will head in reverse towards the curb, in case if It's break fails, and curb should stop it from back from rolling further.
I guess steering away is more efficient because in other case due to weight of car and due to distance(because rear tires are straight) it may gain a little momentum and roll up on the obstacle of curb and may roll on further dangerously. Is this the theory behind this traffic advice and rule?
EDIT I guess the angle of tire with which it will make contact with curb also makes a difference. Front tires makes a better i.e bigger angle against curb and hence may be a better stopper.
