A trail bike rider riding at road speeds, on the footpath, on an unregistered motorcycle. This street is home to many retirees who would break a hip just trying to get out of the way. It’s also just down the street from a primary school. This particular clip will be referred to the police.

First section of the video is from my rear-mounted Cycliq and second section is from my front-mounted GoPro. As you can see I was stopped in the advanced stop box at the intersection, having taken the lane as I was heading straight (instead of left turn) and also because there is a parked car ahead in the left lane after the traffic lights. The motorbike subsequently overtook me from my left hand side in the middle of the intersection and had to switch to right lane after to avoid the parked car.
