I'm baffled by this...
Happily heading along a quiet road this morning, I see a car appearing on the right wanting to turn right into the road we are on.
Natural reactions mean I keep an aye on them. As I get nearer, I see them looking and then start to move despite me about to occupy the same road space. I shout 'woah ' and simultaneously they stop (before really entering the road, let alone my side of it). They raise their hand as an apology and I pass and think nothing more of it and carry on my day.
200yds down the road I hear a beep from behind and it's the same car. No one else is around so I pull in and stop. The youngish chap aggresively tells me not to be so cheeky. And that he doesn't take cheek from anyone.
I struggle for words but eventually manage to placate him, after explaining that of course I was going to shout if I feared for our safety and that I had accepted his apology and it wasn't a big deal as he had spotted us and stopped in plenty of time.
It turned out his bugbear was that on the back of the bike the kids were waving (no rude gestures I hope) at him and pretending to shoot him. They are going through a waving phase so it wasn't personal to him...
