Free buses and bikes is about zero carbon strategies though. There are other considerations behind decisions a lot of the time.
Yes, there's obviously benefit in the zero carbon things, but it's not clear why, for example, the best means of tackling that (admittedly enormous) issue is by giving kids a bike. Especially if they a) don't have space to store it, b) don't have parents able to help them ride it or with the time, or even the bikes themselves, to go off on long improving family bike rides, c) can't get anywhere on it because they'd get squashed by a lorry on the busy main road right outside their front door d) live in Scotland where in many places it's hilly, generally cold and rainy and dark, often a long way from where you need to be and so on.
There's a lot of issues needing solving, some of which will need public money and some can be progressed by pressure on private individuals or developers through improving environmental legislation, planning (insisting new developments have proper footpaths, cycle paths and accessible public transport, as well as better green corridors, outdoor space with appropriate lighting, renewable power, electric charging points and so on...) and so forth. Active travel is important, but free bikes are only one way of possibly encouraging that for some people. It's fair to ask if it's the most efficient way of reaching that aim, given there's only limited amount of money! And it's not just lack of bikes that hinder people not getting in their car, in general...
Also, not sure Scotrail's current consultation of its revised (I. E. reduced) timetable is really in the spirit of increasing use of public transport, generally.. Maybe if we hadn't had the past 18 months of being scared shitless to use buses and trains (and forbidden from them for a reasonable amount of time, unless "essential") people may be more keen to use them...
