Many creative solutions here.
I just want to add my voice,
@Simbalwa, to the set that feels you are feeling particularly entitled, moving of your own choice, and blaming the company that
you bought two luxury cars from for not planning for
your exceptional circumstance. I mean - that's like me moving to the US and blaming the US government for not providing universal health care! Factor the marginal loss you'll incur in swapping your two luxury vehicles, balance that with the benefits you obviously appreciate in taking this opportunity in Canada, and suck it up princess. Or stay where you are - nobody is forcing you to move, especially Elon. He doesn't
owe you a car that satisfies two countries arcane regulations.
Put another way, say it cost a $50 premium per car to make them compliant in both countries ("but I wanna move to the UK!!" someone else says), are you asking each of us to add $50 to our Tesla purchases so you can do this exceptional thing? No thanks, not me, not gunna.
