Roller Coaster Scripting

I’m working on a roller coaster, although I’ve never made one before, so I have a question before I start scripting it. Would it be more practical to animate the cart’s movements alone, and align it up with the track? Or should I attach the cart with wheels and script breaks, boosts (etc)?

There are already many posts about cart tracks and roller coasters on the forums. They all have different opinions and processes.
I’d suggest that you Search for them. You probably get a few ideas about how to make your setup the most performant.
