In my country (UK) it’s entirely caused by a policy that means people in well paid jobs can pay for a lease agreement direct from their salary and save tax. It also can be used if you’re a high earner to bring you back under a threshold that gives you a subsidy for childcare. So if you earn more than £100k and have kids under 5 you are almost stupid not to take a lease for an EV if you have the need for a car anyway.

As a result of the above, EVs that are ~three years old are flooding the used car market and you can pick up a Tesla for < £20k
