EVs have already achieved price parity with ICE vehicles in the smaller vehicle classes. In the next 5-10 years all EVs will be cheaper and better than ICE in almost every way, aside from some niche applications. Battery prices, efficiency and charging times are rapidly improving. And I'm pretty sure solar cars will be the norm eventually.

Under ideal conditions: They already cover the average daily trip length in most places and that will only improve as efficiency goes up for the EV and the solar panels. With 30%-40% efficient panels, the average person would never have to charge.

Of course none of this will always be true on an individual level, but it will be on average.

With high efficiency solar panels and bidirectional chargers, solar cars could become net energy producers.

So in my opinion, even without any subsidies, regulations or bans, EVs will take over everywhere in the next 10 years.
