Here's the problem with widespread adoption and welcoming of EVs to the general populace, at least in the US.
The common person, isn't going to know about charger this (AC vs DC)...what amps....what needs an adapter (what happens when you get to a station, you're low on power and realize you forgot your adapter?)....
I agree that there's a learning curve that very few people know about unless they're BEV enthusiasts/early adopters. The same thing happened with email, texting, smart phones (and will probably happen quickly with Chat GPT)... some people (especially older people) won't want to learn about the new technology and will stay stuck in the past. And the times will simply pass them by...
As for needing but not having an adapter... I guess it could happen, but I just keep mine in my glovebox... It's there if I need it. I actually have two, one I use at home, and the one I keep in the car. They aren't that expensive...
And really? Bring your own charging cable everywhere with you??
Yeah, I don't love that idea, because in inclement weather that means having to throw an icy/muddy/wet cable into my car when I'm done charging. But it's not a thing in the US, only Europe (and probably other continents). It does have some advantages (less cables draped on sidewalks, less worry about EVSE's not functioning because someone vandalized the cable... )
People are not jumping onto the EV bandwagon for many reasons such as these...even if you exclude the higher initial purchase prices, no one is wanting to jump into this with more hassle than they have with their current ICE.
You need the EVs to be at least as convenient as the ICE currently is....range, re-fueling times, etc.
Don't forget cost of fuel. If we require fossil fuel combustion to use carbon neutral fuels, the price of gasoline could be: What does it cost? Porsche pegs the initial price at 10 euros per liter ($44.73 per gallon as of this writing!) but expects efficiencies of scale and technology to reduce that to $7.57/gallon by 2026. (I think 2026 is optimistic, but maybe by 2036...)
If you want the convenience of gasoline and you're willing to pay $8/gallon, I'm okay with that (except in inner cities where ICE should still be banned because of all the other pollutants they emit. We need to remove the hidden incentives by making people pay the full cost of their choice to burn gasoline. That's going to need to be phased in over a decade or so, because you can't instantly add $5/gallon to the cost of people's commute. But $0.50/gallon/year starting now, and use those funds to start building e-fuel / carbon capture infrastructue...
And no...not everyone can charge at home, as that a LOT of people don't have off street parking....rent homes and can't install chargers...live in huge apartment complexes with large parking lots and no chargers...etc.
The statistics I read say that about 30% of Americans don't have parking situations at home amenable to charging. That's a lot, and I don't see much being done to address that need. Some of that could be addressed by aggressive incentives for employers to offer charging at work, but that still will leave a number of people without a great charging solution. I have talked to a few people who own Teslas, but don't have charging at home, who hit a Supercharger a couple times a week. It's not very convenient, nor is it good for the battery, and I don't think the average person would choose to do that.
I would posit that most people are not motivated by climate change and their primary driver of transportation decisions.
High prices and inconveniences are a bit of a hard sell, and I'd think those in govt and in the vehicle business would be smart enough to force this....
I think you're probably right. It will probably take a combination of high fuel costs, inconveniences (like no inner city driving) and out and out bans to completely change people away from fossil fuels. On the other hand, there may be economic influences on automobile companies where is simply becomes uneconomic to offer gas/diesel cars for sale. If that happens, people may find it difficult to purchase a fossil fueled car, and maybe BEVs won't seem to inconvenient then...
