Discription of Events: Young male (high school age?) driver cut me off at high speed just before entering a school zone. I dismissed it and was then surprised to see we ended up next to each other in the carpool line for elementary school pick up. I gestured to let me talk to him and politely said he should drive more carefully. He closed the door before ai could finish my sentence. Reckless, rude, & entitled. Beware.
