I expect all ICEV's to be
I expect all ICEV's to be PHEV's in the near future and expect them to be around for a long time to come. Although solid-state batteries will bring EV's into the mainstream, they'll also improve the electric-only range of PHEV's. Owners can still ignore charging stations, but may use them if they can recharge in a short period of time. If solid-state batteries are expensive and difficult to produce at first, most of them may end up in PHEV's and high-end EV's. A $10,000 premium added to a solid-state EV would only be $2,500 on a solid-state PHEV because of its much smaller battery. The improvement in electric-only range and better overall performance would justify the added cost.
