The car will always get stuck every now and then. This approach has two benefits: it can be unstuck without sending out a physical driver and while collecting training data, and it efficiently lets m humans control n cars with a wide range of acceptable m and n values. It's intended for the ratio of m:n to smoothly shrink as the software gets better, but m will always be greater than zero.
