Roblox Studio has a couple of templates for you to start your work off with an I like the car they use in the "Racing" template. But there is a problem with the fact that it goes from 0 to its max speed instantly. I have a link here to the version I use and I cant seem to get it to slow down its acceleration. If anyone could look into it and tell me what may be the problem that would be great :)
