Some back of envelope estimates: 75 minutes of walking to get to the workplace. Approximately 50 minutes if I go via bicycle (directions are not straightforward for many reasons). This is regardless of weather and/or traffic if on the road. 30-40 minutes if I go via metro + train (the actual trips take 10ish minutes each).
Unless forced to do differently, the most efficient choice is evident. I'm also lucky enough to live inside the city. Commuters that can't work from home have it even rougher, since they live outside and they take up to an hour or more with public transport.
Sure, that's out of reasonable walking distance: Depending on your day, the occasional bicycle isn't out of question. Even in rain. (To be fair, I'll walk daily anywhere that is 30-45minutes most days).
But honestly, the bicycle is cultural as it would be better to prioritize bikes so it is faster. Same for public transportation. Car-first infrastructure and lack of pedestrian/bicycle/mass transit are political decisions.
In fact, people are actually using bike sharing a lot already here since they were first put into practice several years ago (there are stations where you can hop on close to many spots with high traffic).
They've been expanding the bike share things here. I nearly used them last year, but they are even more so now. I suspect I'll bike this summer.
They've had some for years, mind you - but they were really more in the tourist spots. Now they are putting them in next to a fair amount of regular bus stops.
