He certainly seems to have not behaved in the way most of us would expect or hope a neighbour would in that situation.
It is, however, hard to know what other people are thinking - he could have believed he was saving you the bother, he may have a real problem with OCD or some other issue.
I think it is right to tell him that what he did wasn't acceptable, but it sounds as though you should avoid escalating things. Maybe take photos and log with council or just with a date stamp and a friend who witnessed it? I don't know legal aspects of this, but understand why you would want a record in case he does other odd things.
We had something similar with a neighbour who had lived in our cul-de-sac for a while and we had been here about a year I think. My husband calmly showed him the law regarding the situation - it didn't calm him down! I have since chatted to his wife and been as friendly as I can and waved when he drives in/out the street. I think that approach may have calmed him down - time will tell. From what I can gather, he does seem to think others should play by his rules, but we've not had any other issues.
Hope it all settles down for you.
