It's nice that that's possible for you, but I'm afraid it is not universally possible for everyone and everycity. E.g. bike access to our university (plus institutes etc.) when coming from the city is via narrow but heavy traffic road (to university, a bunch of suburbs, two autobahns), or an adjacent pedestrian path (with a lot of studends and badly trimmed overgrowth), or through the hills with forests and no direct path. The solution here would add & maintain bike lanes (or a stand-alone bike road), but for the above example that would mean deforesting and cutting into 2 or 3 km of hillside. And for the duration of that effort, suspending the primary road between the city and {university, one suburb, one autobahn access} which also happens to be the secondary connection to {two additional suburbs, another autobahn access}.
