I see quite a lot of elderly people on buses here in the UK. Not really surprising given that free bus travel comes with the pension.

Quite a few rely on the bus as it's easier and safer than driving. Quite a few of them make an issue of it at local council elections.

I've also noticed here in Edinburgh that parents are relaxed about letting even fairly young children (under 10) travel the bus by themselves.
