I Like the Idea
The cities owning them is a VERY bad idea. Due to human nature political corruption is inevitable and political powers and their cronies will find a way to squeeze every penny they can out of the economy and put it in their own pockets (or Swiss banks accounts.) The government that governs the best governs the least. (In reference to Jurassic Park: Corruption Finds a Way.)
I could envision myself wanting one under the right circumstances but I don't want the government at any level telling me this is what I must choose to have. (Under my current circumstances it would be just plain and completely useless but just because I don't need it doesn't mean others can't have it.) I do have to wonder though, will it come with a trailer that will allow you to pick up groceries?
And if the government wants us to consider buying cars like this - - - make them cheap and make them in America in a state chosen by the entrepreneurs who invest in the companies that build them. If it is a good idea, and I think it is a very good idea for the right people in the right circumstances, and the price is right, and the people like it - - many people will choose to buy it. It's all a question of the individual being allowed to decide what is best for them within their means and needs.
If you want one or could use one, by all means buy one. If you believe others should choose this car persuade them to do so, by appealing to their own self-interest in doing so. Don't violate the human rights of others by telling them what to buy.
Of course there will always be know-it-all elitists snobs who think they know what's best for me (and the world) and will insist on the government buying me one with my tax dollars and healthy cut for themselves.
