the overlay you are using doesn’t have the back of the car so it will look really weird if the car will go to the right more than you have it now in the script - like this (just with the people inside)
I can make you the code but I want to be sure what is the final position you want - or let me know if you decide to use different car overlay.
Also here is explained how to do it if you want to try it one more time.
