I can well remember when I was younger people opening doors before the train had stopped and getting off the train while it was still moving, probably the issue now is more of make it safe for the stupid. As an aside there was a bit on TV (Midlands) tonight about the increase in kids Trespassing and playing on Railway lines and putting objects on the track. So another generation of Stupid is coming along nicely....
