Your vision is too small. What do you think the biggest problem is for deploying transit to suburbs? The last mile problem. You can have a train to the suburbs, but people still then need to drive from the train station to their home. With an e-bike, that solves this problem.

Sure, you can cite some hypermiler that commutes 2 hours across rural land between cities, but now you're just masturbating to edge cases, the equivalent of someone that justifies buying a giant truck because they move a couch once a year.

E-bikes solve the last mile problem of transit. Look at how trains and bikes actually work in countries like the Netherlands. People tend to bike to the train station, ride the train, then take a bike to their destination. With an e-bike, your train stops only needs to be within a couple of miles of both your start and destination. E-bikes make solve the problem of the incompatibility of low-density suburbs and transit.

So what do you suggest? No cars allowed at all? Even in European countries with strong public transportation cars are still useful and allowed (except in crowded city areas). It's hard to imagine life out in the boonies without access to a car...

I think we should pursue better public transportation primarily, but I also think efforts to make electric vehicles better are an important piece of the puzzle to transporting ourselves sustainably.
