How could i get this vehicle to move in a line

I’m making a game and i need this car to move in a straight line, and when it reaches a certain point reappears at the start and does the same over and over again

I have reading a lot of posts and i haven’t found any helpfull ones so help is appreciated
Thank you.

You can use prismatic constraints to make it go in a straight line.

I am not to sure what you want from like a certain point. A suggestion though is to create a part that clones and destroys the car that touches it and places it back to the beginning.

you can do this with animation, I am familiar with animation so if you want to know you can ask me.
