I get the points that you are trying to make but those micro cars are shit for the consumer for those prices. Yes, you have a small car that isn't powered by fossil fuels, but
- You can't transport jack shit. I've sat in the Opel thingy and while it's comfortable for the two passengers you have literally no boot.
- If you consider one of those most likely you live in a densely populated urban area an can use public transportation as well. And one of the last things public transportation sucks, is transporting unwieldy stuff with you. And your mini car doesn't provide a solution to this, so you have to pay a rental again.
- Those things are waaaaayyyy to expensive for what they offer. Atm you're paying the early adopter premium to drive in a speed restricted, range restricted, and payload restricted vehicle for 10k.
I've been riding public transportation almost exclusively for the last 10 years or so and only had to consider getting a car for long distance travel and transporting shit. And at that point you'll be better off spending 4-7k for an older station wagon than those things.
Also I'm not entirely sure how eco friendly it is to buy a brand new mini EV rather than driving around with a 15 year old car where nothing new has to be produced. Depends for sure on the yearly mileage. Which isn't high in my case, but you for sure won't be driving 15000 km a year in a mini car.
If we compare new regular and new EV? Sure, but then I'll wait until real competitive alternatives in the low-price sector pop up.
