Personally, I think using a vehicle as a weapon should mean a complete loss of license permanently, you obviously aren't fit to be on the road if you see such actions as acceptable. But it'll probably be 2/3 year ban hopefully, a fine and/or compensation to victim.

I don't know what penalties these carry and whether more serious charges would have been available.
