A pair of grandparents (I think?) driving on the motorway with two little boys. The youngest, must’ve been about 4 or 5, was on the front passenger’s lap, no seatbelt and nearly naked. The kid was jumping up and down, sticking his feet on the windscreen, had nothing on except for a pair of undies. It was so strange! They took the exit and I happened to be behind them. Stuck in traffic so I got a really good look at them. The boy at the back, about 7, didn’t have a seatbelt on either. Window was wide open and he was half hanging out of it. My sister who was in the back of my car took a picture of them to report them (we haven’t yet, not sure if we should?) If you have parents/friends/family who drive a blue 2007 Nissan Qashqai and who looked after your boys today in SW London. I’d have a word. This was bloody dangerous and unacceptable. I tried to get their attention but they took no notice of me. A close friend’s brother died in very similar circumstances after being hit by another car from behind when he was 6, this has bothered me so much!
