Jackie and I saw a Burger with Italian plate taken out by a silver grey car pulling right without signalling. The car appeared to be trying an unannounced U-Turn and hit the Burger without crossing the centre line. The Burgerwas only doing 10-15mph at the time and the queue of traffic was stationary. Fortunatly the rider seemed to not be badly hurt as he got straight up and didn’t appear to be in particular pain or distress. Jackie and I didn’t stop as we didn’t have a very clear view of what happened as there was a pack of scooters between us and the incident, and the pack had stopped to assist, as had several car and van drivers, and a wagon full of Police!
