"Mass transit": Shared and claustrophobic space with other travelers. "Biking lanes": Requires exposure to the elements. Depending on where you live this is already a non-starter if you don't want to arrive at your destination drenched in sweat. "electro-scooters": I've been on one of these in Vietnam. Doesn't carry 2 adults well and has the same weather problems as the peddle-powered version. "Elevated footpaths": I live in an urban conglomerate in Asia with ~1.1 million people. A typical day of running errands can easily rack up ~50+km of driving because of the distances between either people I know or businesses carrying niche products. There's no way in Hell I'm covering that ground on foot, in 34deg C weather with 90% humidity.
The city in the article is (1) miniscule at ~85,000 people and 15-20km across at its widest and (2) possesses a pretty mild climate. All of the transportation assets you propose as "solutions" are fine....if you live in California or a similar "Mediterranean climate". Most humans don't.
"But privately owned gasoline-guzzlers are an archaic solution to the transportation problem, and they are not effective in today's society."
Why so quick to jump to sweeping, society-altering prognostications based on conclusions which you yourself recognize as applicable to a small-scale and optimal use case?
Your suggested alternative transport means all severely restrict your freedom of movement compared to a private automobile as they come with range and/or comfort compromises. They would shrink the options of citizens for long-distance ground travel as well (say goodbye to road trips).
"Of course this is a very small town and these changes do not scale up as easily as one would like"
Yes, and given that 22% of humanity lives in urban areas of 1 million+ [1] and 40% of humanity in cities over 100,000 [2], it might be premature to call people to political action to hasten the death of the automobile when you don't have a solution that scales well.
