While I like the idea of not needing a proper car, it’s rarely realistic as a person’s only vehicle. Then the question becomes, how many people are in the market for a $25k toy?
I think a main difference is that this is road-legal in the EU (https://microcar-coalition.com/l7e-explained), while golf carts are not.
The jury is still out on how large the market for such a product is.
