Roz.Most of this discussion is/was about the space and the use of it, that was supplied by the Bus Companies/TFL for the use of wheelchairs and the usurping of that space for other uses (Othe than those laid down on notices by the said companies/TFL.The subject of collapsible buggies was introduced to show the change in Baby transport and its effect on bus users of all types of people.What did mums do before the change in Bus spaces.Believe it or not they had large families then.Its not a new concept.I am sympathetic to mums with large families but they are not conducive to the Buses as they are at present.If you wish to see a change in Bus Capacity and the types of vehicles allowed on them then I suggest that you lobby The Companies/TFL/Transport ministers local and national.
