Battery and supply shortages are the least of the problems.
With a heat wave approaching/in progress, Texans have already been warned this week that the grid can't take it and to consider charging EV's during non-peak hours.
What's that, with about only 1% of cars on the road these days are full EVs?
Maybe Texas is an extreme example but sooner or later, this will catch up with every state and province in North America as that percentage climbs.
Everyone thinking of buy an EV because gas prices are sky-rocketing only to then have to trade it in for a gas car because you can't charge it.
