Oddly enough, I was thinking about this the other day on seeing the safety ad on TV where the bloke loses patience at the crossing.
There is a simple answer.
Over here, the lights flash, the bells ring and then the barriers go down. Somewhen within 30 seconds later a train passes and then they go up as soon as its tail is through the crossing. If two trains pass in opposite directions within a couple of minutes, the barriers go up, a couple of cars pass through and then they go back down again.
Everyone knows that there is no "wait time" to gamble with, there's almost nothing to be gained by beating the thing and that trying to do so is very likely to ensure that your journey ends at the mortuary. As a result, nobody plays silly beggars.
