No, Slobodan, I shan't let it go.
I spend a good deal of my working life dealing with people who have been seriously injured, or with the relatives of people who have been killed, in road traffic accidents. Cars are invaluable - I certainly couldn't live without mine - but they are very dangerous. Momentary lapses in concentration can have catastrophic effects.
If OnlyNorth persists in doing what he is doing, he dramatically increases the chances of his causing an accident with such an outcome. The maximum penalty in England for causing death by dangerous driving is 14 years in prison and for causing death by careless or inconsiderate driving, 5 years: I don't imagine it's significantly less anywhere else. The penalty would be of interest only to him, of course, and to any relatives he might have.
However, I also wonder how he would attempt to explain, just before he starts his sentence, to children whose father he has killed, or to parents whose teenage daughter he has rendered brain-damaged, wheelchair-bound and doubly incontinent, that those are reasonable prices for them to pay for his pointless (and I don't shy away from that description) attempts at "art".
Even if he were producing something worthwhile, which (in my opinion, of course) he isn't, there would be no conceivable justification for the way in which he is doing it.
I entirely agree with the scenario in your penultimate paragraph, with one simple proviso: if it's safe, you pull in to the side of the road, stop the car and put your emergency flashers on before you start fiddling with the camera. If it's not safe, you shrug and accept that there will be other opportunities to take a snapshot. It's hard to appreciate a photograph when you're dead.
I do appreciate your courtesy, however!
