Definitely a London thing! Or in fact, any big city where there is crowded public transport. I walk 45 mins each way every day because I can't stand the bus. I used to have a 1-2 hour tube ride each way before I moved job. I would get totally freaked out unless I could get a seat and bury myself in a book for the whole journey.

It's not just us PTSD people though. I know tons of people who walk an hour or more just to avoid the crowds.

You are definitely not alone.
