There should be a general speed limit of 20mph/30kmh on city streets.
Also no parking on public space for any vehicle that isn't for deliveries, emergencies, trades, or people with disabilities.
If you want to park your car at home, or want your customers or employees to park near your business, you need to buy or rent space for parking privately.
Any citizen documenting a parking infraction with photo evidence should have the option of giving police their bank details and will then receive part of the paid fine.
Of course there will be valid exceptions, like a private emergency, moving, a woman in labor, and such.
Just imagine what our cities could be like if there weren't long rows of cars parked along every street.
The freed space could be turned into bicycle lanes, wider sidewalks, outdoor seating for cafes, green lanes, urban gardens and so much more.
Car lanes could be separated from bike paths and sidewalks by hedges in most places.
Children could play and move safely in public.
The US homesteading is not the standard in a lot of places. Loads of places put all the houses together in a little village and the farmers go out to the fields instead of living isolated at their farm. Also, you have to remember that if we actually did outlaw private motor vehicle ownership, commercial transportation would explode. Much, much smaller towns would have access to regular bus and train schedules. Furthermore, the business landscape would change and your standard stores would again be more accessible in smaller towns.
Would there be some disadvantages? Absolutely. Would there be some advantages? Absolutely.
I consider the advantages to be more than worth it, even in the more trying situations.
I see you there planning using that trash money to fund a weed growing operation! Before we know it people will be turning into glowing cyclops! cyclopi? cyclopses? (Seriously on that last part whats the plural?)
