Okay, if I ruled the world, I would introduce compulsory classes in respect.
When I was a kid, if I sat down on a bus while an old lady was standing, my mother would take the side of my face off.
Too many times these days, I see mothers with children and the children each have a seat, while old people are made to stand up because there are no more seats left.
The mother's argument? 'I paid a ticket for them, why
shouldn't they sit down?'
Erm, maybe because the old people have trouble
standing while your children
DON'T! 
I'll make this a two-fer. I would also make it compulsory for all drivers who want to turn a corner to actually
use their indicators.
I have seen people turning into a side-street with no indicators at all and almost cause a crash because the guy didn't let anyone know what his intentions were.
I myself was almost run over by a van who did this. He was already halfway past the turn, so naturally, not seeing any indicators flashing, I assumed he was going straight on - only for him to suddenly turn into the street nearly knocking me
over.
I was wearing my steel-toe-capped boots at the time and I kicked his van, putting a nice deep dent in the side of his van as he just missed me.
