Not sure about interesting but I witnessed two rear-enders on the relatively short drive home from work today.
First one was a bad one just before a construction zone on the highway. Older Toyota Corolla slammed into the back of a relatively new Jeep Wrangler. I was quite a distance away and just starting to slow down for the line of traffic clearly queuing up ahead. I noticed the Rolla coming in hot but someone pulled in behind them and started to brake, which blocked my view, but it looked to me that the Rolla didn't even apply the brakes before it slammed into the Wrangler. Just hope the Wrangler riders noticed it coming and braced for impact! Air bags deployed in both vehicles but likely some serious injuries there.
Really surprised there weren't more vehicles involved but the Wrangler must have left decent room between him and the vehicle ahead, so good on them if that's the case.
Second one was just after I exited the highway. There's an intersection just after the exit with traffic lights. Light turned red as I was approaching so I was stopped. Noticed the first guy up on the other side in a Taco was texting when the green light started flashing and the guy behind did the classic amatuer move of paying attention to the light instead of the vehicle ahead and ran into the back of the texting dufus. Just a light tap but still some damage done. Some shared blame there for sure.
Anyway, bring on the collision avoidance systems.
