Get rid of the tax incentives. If a product is good, it does not need tax incentives. An incentive to owning an EV include the low cost of operation. I read an argument years ago that incentives tend to go to the folks who least need them. Do Tesla owners really need that few thousand dollars in tax breaks? Seems like that is basically a gift to Tesla from the government.
For a good number of people who live in a situation where charging is an issue it makes sense not to consider one. Unless apartment complexes invest in putting in charging stations, that is going to eliminate a lot of buyers. Many city dwellers may not have access to overnight charging either. I think about my friends in Chicago who own cars and street park. Who is going to put in the charging stations on all those streets in large urban areas?
I get the fear people have about range. I suspect folks are thinking of that one or two times a year where they drive farther than the range of a single charge whereas the vast majority of us would not expend a full charge in a week. My sister just ordered an EV. She did the calculation and research, and for a long drive she regularly does (4x a year at least), she can make it with one 30 min stop and there is a charging station situated perfectly.
The big area where EVs can have an impact is on fleet vehicles. The US postal service is going to buy many. Fleets are perfect for EVs and most stay in one spot overnight and from what I have seen can do their duty on a full charge easily.
