I'm not sure what's the definition of an "ordinary worker", but as an electrician in Denmark I could absolutely have a Tesla if I wanted to. Which I don't, I really like my Leaf.
So in the UK most sparkies (as we call them :D) probably could as well.
But what I think people in the US (and many in the UK) don't grasp, is that someone (plucking an example out of the air) who is a manager of a retail shop in a small town in Sweden could afford a car like a Tesla. Partly because of the strong democratic socialist economic historical context underpinning decades of economic and workplace policy, and partly because of the decades-long subsidy and support of EV sales and supporting infrastructure in these countries making them cheaper and more practical than in many other countries.
This couldn't be further from the truth in the USA, because work life there has been going in the opposite direction effectively since the cold war.
Depends on what you mean by ordinary workers. But a lot of people can. A Model 3 is not a status symbol at all. Same with Model Y. They're just.. People movers. What makes Teslas expensive is its repairability, and therefore insurance.
And a family might not have more than a single car, so it might be two adults paying for a single car. We only had a single car in the family when I was growing up.
