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.

Safety is definitely the tough part, and would probably require a new innovation in safety tech.

Maybe if you could find a way to create incredible traction between the tires and the road in emergencies you could stop faster and offset the G force when someone crashes into you.

Exterior airbags are also an option - basically just deploying a tire sized thick rubber balloon the instant before a collision, from both vehicles.

Or if the car is light enough, maybe it could jump.

Or like that table saw that stops when it hits flesh , you could have a break bar shoot down out of the bottom of the vehicle to jam into the road. Youd damage the asphalt but better some chunk of asphalt than a persons life.

Requiring CDLs for these huge monstrosities would finally put pressure on automakers to return to more reasonable car bodies and it would make sure that people who have to drive big vehicles at least are qualified to do so. Traffic tickets should also scale with the size of the vehicle since a speeding Range Rover presents different risks to the public than a speeding Smart Car.

Real investment in walkable cities and suburbs is the harder solution but the better one. If you could walk your kid to preschool that eliminates a car trip. Walking exposes you to the elements, but walking speed doesn't amplify rain, cold, or heat like biking does. Zoning laws should allow a preschool, a grocery store, a pharmacy, a community space, and a hardware store to exist within easy walking distance for you. Bike paths should connect you to the next community. Miles of uninterrupted residential-only zoning is choking our planet.
