15.5 million cars are sold in the US every year. It may be an increase, but it is still a drop in the bucket. I do not have access to private parking and consequently have no interest in buying a plug-in vehicle until I can cheaply and quickly charge it somewhere else. I do not expect do live that long.
A great many things needs to happen for the plug-in EV to be considered the default option for every driver in the USA. I have doubts a healthy infant born yesterday will live long enough to see that day.
We will need a large expansion of electricity production. Presumably electricity production based on something other than fossil fuels or we are just shuffling the problems around than gaining ground on air pollution, energy independence, and CO2 emission reductions. We've certainly seen large gains in wind and solar power but that's easy when they effectively started from zero up until a decade or three ago. When did the push for wind and solar really take off? I can remember hints of this in 1980s era TV show re-runs, some of those hints weren't exactly subtle, so maybe I'm off a bit on the start of this all.
We will need large expansions in mining for all kinds of minerals that electric vehicles depend on. Rare earth metals aren't rare but they are difficult to refine. All rare earth metals, at least in the USA, is something of an afterthought on mining for copper, gold, silver, uranium, thorium, or so much else. We can already dig the metals out of the ground but we need refining and manufacturing to turn those metals into motors, batteries, inverters, or whatever. That will take time. Much of the same applies to other minerals, and to the materials needed for electricity production.
I'm likely missing some other dependencies on adopting electric vehicles in the USA. We will need some changes to rules, regulations, and legislation but that's something I'd believe is not time limited. The same may apply to infrastructure, we have wires and such already in place that may be sufficient and so not likely a limiting factor.
If there's still issues on overnight parking and charging once the matters of materials and manufacturing have been worked out then we screwed up somewhere in a big way. One mitigating factor on this is that we already see people reporting to be able to complete their daily commutes with a once per week recharge. This can mean some piling up of people at public recharge stations on weekends but I would expect some shifts in expectations, habits, and so forth to mitigate against the worst of that. One outcome might be some kind of renting out private EV chargers if there's some kind of seasonal shortages, much like people renting out their front yards for parking when there's big events in the area.
People expecting wide adoption of BEVs will have to moderate those expectations to real world limits. People expect their cars to last 15 years for one. Then is infrastructure changes which can take decades. Shifts in manufacturing and mining can also take decades.
Decades. Potentially many decades. This transition will take decades, assuming we don't come up with some other option like synthesized fuels to derail the shift to battery powered transportation.
