Single-payer transport, just like single-payer healthcare. That said, I would like to add an anecdote to your P.S. I commute to Copenhagen, so I take a train and then a bus to reach my destination. I have a travel pass that lets me take public transport for free in a specified region. Copenhagen also has a bike sharing system, but using the bike sharing system costs money, even with a travel pass. As such, I'm incentivized to not use the bike sharing system and take the (usually crowded) bus instead. In fact, I know of no one who uses public transport for some part of their journey, who also use the bike share. People either live within biking distance, and therefore use their own bikes (unless broken or for other reasons unavailable,) or they live far enough away that they need to take some public transport no matter what (my situation,) and then just take public transport the entire way. In the end, the bike share mostly just gets used by tourists, when it could very conveniently replace the bus for last-mile transport for many people.
