depends. if I can use one of the vertical bars, going from the floor to the ceiling, I do that. but there’s a lot of space between them (not every seat) and I’m a short person. I can reach the loop, I can’t reach the handrail the hang from. so if the bus is crowded, I’ll wind up on a loop.
luckily, I get on my current daily commute early enough to grab a seat most days, but a previous job had me hanging from the loop every day.
