Sadly this is not new. I remember a similar incident to MTB-idle’s above whilst out on a club ride 30yrs ago. Unfortunately for the driver in question, the club “hothead” was targeted. End result was that the car was reeled in at the next set of lights, and a loud bang as cyclist rides past. Driver drives off, possibly unaware that a screwdriver had been rammed through the roof and disappered into the distance with the handle sticking vertically from the roof and the shaft going straight through. I remember feeling shocked at the behaviour of both at the time. Hopefully, with headcams, recording and reporting will result in a more mature retribution. I’d be interested to hear what outcome prevailed in MTB-idle’s case. Hopefully, the perpetrator received more than a dressing down.
