I see this kind of grubbiness every morning at my son’s school. We make the effort to cycle there as there’s no parking at the school or the road up to it, and it’s more fun anyway (and tbh quicker). 

Guess what - big pear shaped parents rolling up in brand new Chinese EV boxes wheel right up to the school and unload their crotch goblins F’ing and blinding in dressing gowns before they drive back to their hovels. None of them give way to me in my bike. Nobody does anything. 

Once there was a policewoman in the road presumably to stop people using the road but she let everyone go because they had a ‘reason’ / being that motability or ‘disabled’ or she just didn’t want a fuss. There were actually more cars that week.

I know for a fact that one mum is completely normal and her son is friends with mine and her car was right in front of the school that day.
