Normal? No. Too common? Yes. A minority of motorists always will be idiots and they seem more common on some roads than others. If roads ever gridlock, then that seems to make more motorists stupid too.
The proportion of them seems to vary around the country. Even in relatively cycle-using King's Lynn, I used the road to the leisure centre early yesterday evening and a 4x4 driver was so incensed by me riding to the right of raised ironwork that he "punishment pass"ed me and that wasn't enough for him, so after we'd both parked at the end of the road, he walked over to the cycle parking to criticise my riding. When it became clear I was both unapologetic and bigger than him, he walked off with "learn to drive" ringing in his ears... not my finest moment, but stick to your line, eh!
If I wasn't daydreaming, I'd use the near-parallel cycleways. It's no further, avoids two sets of traffic lights and is full of happier people who haven't had to deal with motorists like that 4x4 rager, which I guess would annoy anyone
Shame I didn't have the camera on (local police say they're interested in road ragers), but I'd probably have stopped it when I parked anyway.
I think: don't let the nobbers stop you riding properly but don't respond in kind, consider a cheap camera if you can afford it, grass up any bad drivers and report the worst routes/times for it to the police because even in these times of cuts, I think they still like shooting fish in a barrel to get the numbers of solved offences up.
