Until it breaks a kid's neck...

A kid could break their neck in a bus door which can be quite
violent. Perhaps you could campaign for them to be made out of
marshmallows with cotton wool sides?

They already close quite hard enough IMO.

Well I can hold a tube door open with 3 fingers so unless you're a
3 stone midget with a muscle wasting disease I hardly think they close
hard at all. Besides , I'm sure other countries have had the usual
"think of the children/pensioners/some-other-sobsville-group"
argument and ignored them. Just like we should.
