This was me coming thru a tunnel on the parkway last week. I had hit the airhorn to see how much the wife would jump at the echo, laughed at her and exited the tunnel to find carnage. Three cars, two bikes, and a hiker in a pile, parts scattered everywhere. The first car upon hearing the horn and seeing a single yellow light thought he was meeting a freight train panicked, locked the brakes and lost control wreaking havoc. Three cars, two bikes, and a hiker in a pile, parts scattered everywhere. Luckily no injuries but it took two days to figure out which parts went to which vehicle. Lawyers are recommending I add more lights to look less like a locomotive. The best news out of it was that me hitting that broken truck bumper shook two lost 10mm sockets from somewhere in the motor and landed on my floorboard.
