When a player enters a vehicle, how would it work?
When they get in any vehicle, tells them to "/start", but, if the vehicle is running? How would this all work?

you use a variable right when the engine is runing the variable checks for the vehicle ID and gives a value of 1 for on or 0 for off
so when player enter the vehicle it will check for that value and see if engine is on nothing happens and if engine is 0 = off
it will do the action and message for /start
