Don't people slow down and they look?
Whenever I'm driving around the USA I'm always concerned even if the level crossing has gates, they might fail. I always slow down and look even if the gates are up. But to be able to see far enough down the tracks, the front of the car is often on the track already. School buses have to stop before crossing.
On my recent trip to England in the Alton area, I don't remember going over any level crossings but everyone else was driving on the wrong side of the road
