Imagine that you need to cross a multi-lane highway, where cars of various models and purposes are constantly scurrying around. Every driver is in a hurry about their business at Cars Don't Stop, and since there are no traffic lights or pedestrian crossings, they are not going to stop just because you suddenly decided to cross the road in this particular place. You will have to act at your own peril and risk, and take responsibility in case of an accident. The goal in Cars Don't Stop is to cross as many road lanes as possible without getting hit by moving vehicles.
