This car has keys, speed and fuel systems. Turn the key with "RIGHT". It will make you speed up. Stop the car with "LEFT". It will completely re-lock the car (because of the key).
During the voyage, the fuel arrow will slowly go left. When you reach 0, nothing happens. The arrow just returns to 1. I can't make a system to completely stop you.

Notice: Yes, i know, the arrows get out of the speed/fuel systems. I tried to stop them (it worked for the keys), but when i tried the EXACT same thing, it simply didn't work.

So it is useless to comment "the arrows bug out" - I know!!!

Have fun!
