There's an additional point that if you were to accept the "principle" that trains should carry "scooters" (or mini 4 X 4's as I think of them) how many would you carry? And if it was , say, a crammed 2 car car unit Leeds to Harrogate in the rush hour and the person with the "scooter" got there before the punters, which one would give way?
In a situation where you had to evacuate a train because of fire how would you deal with it and the obstruction it would cause?
