"Just hope some MPs (and MSPs) have also contacted him about 'active travel'."
Indeed. What are the chances though, I wonder?
Presumably the MPs/MSPs contacted him about buses as they're reacting to a palpable crisis (arguably been going on for years, but now it has reached a tipping point and services are finally being withdrawn).
"Active travel" is a bit less tangibly in crisis from your average politician's point of view I suppose. Measurement relies on annual stats, no depot closures or job loses to react to, no little old ladies in villages losing their lifeline link to shops in town. If a bike shop closes, that's "just business". If some cyclists are killed/maimed in collisions with motor vehicles, there's alway the "who was to blame?" conundrum. If not "enough" people are cycling, one can always blame hills, weather, laziness, having to wear lycra/polystyrene hats. As for walking, I imagine people struggle to see that as "transport" because that usually involves a vehicle in the mind's eye of many/the majority.
Sorry, bit Devil's Advocate here, but you can see why buses might get onto to the "to do" list rather than "active travel".
