The alarming thing about this is it was a "
SCHOOL BUS". This is someone we all trust to keep the most precious things in our lives safe! No second chance for this arrogant fool, report it to the police anyway before it ends in tragedy for some poor family. The bus company will know who the driver is because of the route he was on & they are obligated to give up the information to the police.
It's the best form of road rage you can do & you won't get into trouble for it
