I think you're right. Here in coastal NorCal, I know a ton of people who are very interested in an EV but can't afford them. I've converted a couple to used Leafs, but these incentives are a big deal to them. I bet the story is different in the Central Valley.
Not enough data, is there?
Anecdotes from the Central Valley:
Where we live in the northern part of Fresno, we see Teslas every day cruising along Herndon Avenue. The Ranger believes that there are ~250 Teslas in town.
The landlord for the newish outdoor shopping area recently installed six ChargePoint 30A free charging stations. I go by there occasionally and find the usual mix of Leafs and Fiats and BMWs plugged in. I spoke to a retired Hispanic man last week who was charging his Leaf. He had just leased a Bolt, and he and his wife love it. The Bolt battery lets them drive to their mobile home in Oceano without stopping. He said they leased it because technology keeps changing, so why tie up 30K when a 3-year lease would let them decide what to do when the lease terminates.
We have spoken to three Fiat drivers and they all said that the monthly lease payments of under $100 were too good to pass up. All three drivers charged in their garages on 120V circuits, and overnight was always enough for their next day's commute of 20-30 miles. One person had the availability to plug in at work; two did not.
I spend some time in Modesto during filing season. There are virtually zero BEVs in that town. There are also zero public charging locations besides the car dealers on McHenry.
I come away with these non-scientific, purely anecdotal conclusions:
----Lease incentives will place more people in BEVs. People with much more limited means and a shorter daily commute for work and errands.
----Availability of public charging stations at locations to do things while they grab 10-20kWh of electricity will help convince the masses that you can keep your car fueled while doing other things.
----Ever advancing technology lends itself to leasing over buying outright. Most individuals of modest means finance their cars, and they hope to be able to drive the car for years after they have the pink slip. If lease payments are equal to or beneath the monthly car payment stroke, why not just lease? Then after the 3/4/5 year term, turn the car in and get the latest and greatest.
The bill should be written so that any rebate could not only be applied to an outright purchase, but could also be used to reduce monthly lease payments.
