I've long wondered if it is the USA's lack of roundabouts compared to the UK that causes many Americans to grow frustrated sitting at red lights when there's no traffic driving across them on green that makes them conditioned to drive through red.
My neighbouring desk for a year for a hotdesk to the visiting American on a two-week tour of duty. For many it was their first UK visit. The majority liked roundabouts after a couple of days, preferring them to junction lights.
