How do I make Bloxburg-type vehicles?

Hello, Roblox Developer Community!

Recently, I have been looking far and wide for a solution on making a car system like the one that Bloxburg has. This would be simple, have no visual displays, no gear shifting, car stops automatically when you stop driving, car always has the same speed upon pressing the keyboard key - or no acceleration, and no physics. Basic system! If someone could give me some help in how to achieve this since Roblox does not really have their own system on making vehicles, that would be much appreciated! Thanks.
