Indeed. I've lived in the UK my entire life, and I've only ever heard "sorry" used to mean "excuse me, can I get past please?" in and around London. It still sounds weird to me. Where I come from (further from London), you'd just say "excuse me".

Not quite. If you had to get off a packed bus with a large rucksack I'd certainly be saying sorry and I'm from Yorkshire.

Glaswegian here, I would use sorry as an "can I get past" also.
