Price for a much bigger Fiat 600 hybrid is 24k EUR, a Fiat 500e is 30k. You get less range, less space and at current electricity prices you pay more if you charge at home than you would with a if paid for gas for the 600.
Why would anybody want that?! If they were 20k it might be interesting but they want 200% profit margins just because EV and then act surprised nobody wants it. Fuck them.
Just restrict network access (both in and out) with proper (trusted) hardware firewall. It's much safer that relying on disabling / configuring etc. You can't attack what you can't reach (directly or in reverse).
