Bumping along on my golf cart isn't much fun, but is there a way we can design it to control / limit speeding? It's like a race car track out there!

PS: Not a big fan of the speed bumps recently installed in town near the schools (the idea is a good one!), but they don't seem to phase the larger vehicles / Taxis, but will surely tear up some golf carts (at least mine as I have to almost stop completely)...
