Re: the train willl bring itself to a gentle stop
"Trouble is, that distance is often big enough for the person behind to want to fill it."
Someone *always* moves into the safe space I leave between myself & vehicle in front on UK motorways (never lucky enough to travel on the roads at a time when traffic density low enough that it won't happen).
But in UK, traffic police numbers are very low so you can get away with all sorts of inconsiderate driving as chance of getting caught minimal ("tailgating" is very common).
Only thing they bother about in UK is speeding (and that's mainly via automated camera systems, get teh occasional mobile police speed traps too)
