I don't see what the problem is. If they're going slow in a super-market then, regardless of their mode or make of transport, is that not a good thing? If he were to drive in a dangerous, anti-social manner I could understand, but come on.. who cares what car they own? If they like it and they are hurting nobody then fair play to them?
This needs filming as potential evidence. Throwing items at someone is also assault..and people have been convicted for it. If what you say is occurring on a regular basis then it should be easy to film - use anything. Get witnesses. Then call the police. If they try to squeeze you off the road, make sure you ride primary (aka taking the lane). Let the driver make it worse for himself, if he must, but never ride in the gutter. As mentioned, witnesses and footage are crucial. Stay safe mate, all the best.
Get a camera & film them.. they clearly want attention, right? Maybe they'll see the vid and realise the mistake. I get these crap passes almost every day on a bike..some driver's comprehension of the highway code is simply dire. Take care.
You're a sensitive soul, they are white man vans, they are everywhere driving up folks rears. Don't dilly dally when overtaking, surely you could have been going 70mph?
