You did kind of cite the actual issue, the one we want to fix, right in your complaint. A well-funded subway/bus infrastructure tends to suit most people's needs, such that the short trip to take one of these dinky ebikes/e-unicycles to the train station (or, taking a frequent bus on its route) would rarely be so uncomfortable. The key here is that climate-controlling an individualized vehicle is going to be inefficient no matter what.
The environment will always be a potential concern. If you live in a rainy area, but vacuum-seal yourself into your hamster ball before heading to work, you'll still need an umbrella after depositing your hamster ball into the Ball Collective before going into the office building. From my point of view, it seems like you're pushing the "problems" into the wrong domain of concern, and also kind of pretending cars solve that issue 100% - which they don't.
