Does this car have a handbrake?
No, but if you keep pressing the footbrake it won't go anywhere.
But isn't there an easier way of stopping it from rolling away on inclines?
Well. If you buy an 18-wheel semi-trailer truck, learn how to drive it with it's 10 gears & hi-lo ratio shifts, and arrange to park it wherever you want to stop in your car; then if you park your car uphill from it, it won't roll very far.
