It can still have nice comfy seats and music, and be a good place for people to meet. It’ll have the advantage that people always know where it is!
It will have an engine which may seem a bit pointless. The car will rarely need to be filled up with fuel – so rarely that people may argue over whether being filled up is something which only needed to happen once or needs to be done on a regular basis. People probably won’t remember the last time you needed a refill unless you’re running the lights, music and windscreen wipers an awful lot.
