I appreciate that utilised public transport is a good thing but when it is crammed full to the point where safety is an issue (having to stand right against the windscreen) then I think there is a problem.
There is no way private hire coaches would allow schoolchildren to travel without a seat and I think they even need to have belts these days. There are times when I do not feel safe on the P4 bus.
I would love the luxury of walking to work but this is not a realistic option for the majority of people living and working in London.
