Scary stuff... I have never seen a cart engulfed in fire, but have seen a couple that were pretty scary. One was gas and had run over something flammable that stuck under and was burning. The other was an electric Par Car that had some connections so hot they were beginning to smoke. Both cases were caught before anything bad happened.
If you drive electric, keep your batteries properly watered and check the connections as part of your maintenance.
If you drive gas..........ummm..... well how would I know?
You like playing Wheel of Fortune?
What do I call a gas cart that completely burns up and cannot be used anymore?
Oh, cmon... I just having fun
PS. Of course I do not wish anyone's cart ever burns up....
