or, get a bike. healthy, no emissions, and on top of that, cheap.

True, but not everyone lives close enough to work or is in physical shape to bike. Most people should, though :)

The bikes are nice idea, but hardly panacea. You need to design the city around it (costly, conflicts with other usages), isn't possible for variety of people (age, disability, distance).

I used to drive 40km to work every day in single direction. Not gonna happen with a bike.

Electric bikes are a thing ;P
