The new Routemasters are small because they have to be. They are used on services that include roads that normal size double deckers cannot easily use. That is why bendy buses were tried, they are more maneuverable, but their length caused problems for other road users and they tended to end up bunched together. On some routes they were replaced by single deckers on others the new purpose designed Routemasters. So, not a vanity project, but required for s specific need. I welcome the Garden Bridge. Yes, of course the money could be spent on other more worthy causes, but that is always the case whenever a new high profile development is mooted. No wobbly bridge, no London eye, no Tate Modern, no Globe Theatre, no Borough Market, no South Bank Centre. The place would be dull and grey but terribly worthy.
