One thing to consider is that a lot of stuff works well for electric cars simply because they are not that ubiquitous. For example, many states allow them in the HOV lane unconditionally. However, if they are a higher fraction of the total cars that will stop. I have seen electric car chargers at various parking lots. If you have an EV, you are likely now to find a spot. When they are a lot, the majority of EV won't find a spot. The other issue is overnight charging. People who live in apartments will have trouble finding charging spots, when nearly everybody in their complex also has an EV. In addition, the spike in nighttime power draw on the electric grid is going to be an issue, especially in areas that are dependent on solar power.

I think a large part of the driver for EV currently is as a social status signal. When, that start going away and the inconveniences of EV with respect to ICE start affecting people, a lot of the momentum will stop.
