It seems likely that BSJ will - if he survives brexit - embark on some giant vanity infrastructure project. At one point I thought there was a possibility this might be something cycling related, but since cycling has been dropped from the Boris brand image, it no longer seems likely.
Beyond that, what bludger said. Cycling, where it appears on the radar at all, will continue to be an underfunded local authority thing. And those of us who are members of disadvantaged or minority groups are likely to have other things to worry about.
