Having my car hit in a car park recently, seeing this make me pretty mad, how can people be so inconsiderate, she didn't even look at the car she hit in front. I'm not the best at parallel parking because i never have to do it (drive way at home and car park at work), but if you just take it slowly it's pretty simple. I can imagine sensors being good in vans with no back windows or lorries though. That said, how often does a lorry need to parallel park?
