The guy ended up going away, but 3 days later this same maniac followed DH home on foot while he was walking home from work, ended up confronting him in an alley way and urged DH to fight him.
DH told him he wasn't going to fight him and to back off. The guy quickly pounced on him, got DH to the ground and kicked the crap out of him.
This psycho wasn't properly punished by the law and he is still freely roaming the streets.
So please people, be careful, you never know how crazy some drivers can really be.
