Assuming the competitors comply with the law then afaik you can race cars to your heart's content - but it wouldn't be much of a race as you'd be complying with speed limits etc.
Actually lots of/most bike races are done on closed circuits, but the difference with a "proper" road is you get the variety of terrain, which as bikes are people powered makes a massive difference - look at the ToB stage through the Lakes - Honister Pass, then a blast along a fast road and then a steep finishing climb - most closed circuit races are settled with a sprint as you can't get away from the group.

I'm not aware of any club races on closed roads. If you mean Sportives I think there are four closed road events per year in the UK, all in different areas, plus the ToB and some town centre races like the Otley races, where the circuit is maybe a mile and a half long and not very hard to get round.
