You can a sense of the demand by looking at the resale value and time the car is sitting on the dealers lots.

In the UK, they can't keep stock of used Leafs and other used EVs. Starting to see that trend in North America albeit a slower pickup. Good value in used EVs, especially used Leafs if the capacity can work for your use case.
I just bought a 2018 (151 mi / 40 kWh) and I couldn't be happier. This market is changing so fast, I think there are a lot of folks like myself that don't want to pay full price. So buying used makes sense until the market matures, range goes up, infrastructure is more built out and prices come down.
