It kinda depends on what you mean by "solved". You could have a bus route stop at every person house. This would be expensive, frequency would be abysmal, and the routes would take forever and no one would use it.

This issue is that public transit thrives in areas with more density. Get rid of the density public transit ceases to exist.

A more realistic solution for most people would be to try and set up a bike network throughout the neighborhood. Biking, especially e-biking, is mode of transit that can be implemented almost anywhere in a city and have some big benefits to the citizens.

Staple racks should be the standard for any business that cares about cyclists imo

I think it depends on the work that you are doing. I'm currently working as a journeyman and the most I need to bring is my hand tools. If you need to carry more the company will likely give a vehicle, but the vast majority of people drive their personal vehicles only to transport themselves and their hand tools.

I actually changed these to 2 inch wide tires with zero issues. The advantage of thicker tires is a smoother ride with the added cost of more weight (although on an ebike this is much less of a problem)

Friend of mine just released Terrytorial Disputes. Not exactly C&C, but heavily inspired with a mix of tower defense. It's got a free demo if you want to check it out
