A few years ago, driving home from the winery with the whole family in the car, I noticed the car behind us drift off the road a bit. As in way off - squarely whacking a mailbox at 55-70 mph. And he didn’t stop. At the next stop sign, he was creeping up on my bumper, and I could see the huge hole in his windshield in my rear view mirror. I deliberately started slow when it was my turn, and sure enough, he jumped on it and bumped us. I stopped and put it in park. He started to back up (presumably to go around) and the pickup behind him pulled up tight so he couldn’t. I got out and chatted with the pickup driver, and called the police. Then we both waited for them to come and collect the very stoned driver. The mailbox has gone through his windshield and was sitting in his back seat. He hadn’t noticed. He told the cops that maybe he was having a medication interaction- but the fun little ‘pipe accessories’ in the front passenger seat didn’t impress the cops.
Man, did people trying to get around us in that intersection yell nasty crap at us- but I couldn’t let that kid drive any further.
