Maybe where you live, but I would disagree it's the same everywhere.
And with a global shift towards fossil fuel free vehicles, governments are already involved, so one more little thing isn't going to make any difference.
Just like there are charging standards, even though they aren't global, there should be "easily" swappable battery standards. I don't expect this to be something you can do on your own, it's not a Gogoro scooter we're talking about here after all, but something a qualified mechanic should be able to do in a day at the most.
With all the talk about the environmental impact of producing cars, you'd think this one would make a lot of sense, as it'd give electric cars a much longer life span.
