Making a car without a VehicleSeat?

I have seen a couple games do it but I could not find any recources on how to do it.
Was wondering if anyone could shed some light?

Only other way is by making your own technology to create a car seat, even then it takes a while.

Make a normal seat.
Seats have the property “Occupant”, which is the player object who is sitting on it.
You can clone stuff into the player, like holding W to go forward, S to go backwards, and once the seat object has changed, you just delete the local scripts from the player.

Vehicle seat is used as a shortcut, you do not need it to create custom vehicles.
