What about this for an absolute loon. Crashes and waits with part of his bumper to throw at an opponent. Could have killed someone the muppet. https://www.bbc.co.uk/sport/av/motorsport/54421361.
Then he kicks off in the pits after the race. Apparently, he has now given up the sport after his shocking behaviour.
I have seen it . Apparently his dad owns the circuit and got involved at the end too . I do remember a similar incident a few years ago in an American dirt race and the driver got killed when he went on the track by I think Tony Stewart ( NASCAR driver ) .
I remember seeing that at the time. You're right it was Tony Stewart and I think he may have retired after that incident. https://www.google.com/amp/s/amp.usatoday.com/amp/512002002
