Here is another thought provoker. I have a new house that has 2 200 amp panels and presumably 400 amp service to the house. A lot of smaller older homes have only 100 amp service or 200 amp service. We had a single 50 amp plug in the garage in case we ever bought a plug-in electric. That should support a 10 kwh charger Good for charging a 100 kwh battery over night. We have 3 cars, and may have as many as 4. Once we get past one car we have a problem. If we have 4 electric cars (one on the driveway) Now it is very bad situation with significant rewiring and on summer night with 8 tons of air-conditioning running we would be pulling over 200 amps continuous. Theoretically we could do it ( adding more 220 circuits) but a LOT of houses could not.
It is not just electric companies building new infrastructure, it is rewiring a lot of houses too? What about apartment complexes or apartment buildings? Street parkers in large cities? Minnesota at minus 27 degrees and parking in an apartment complex (yes I lived that). The practical logistics of a full conversion, even over 30 years is huge. How will it get paid for?
What kind of range will you have when your car has to sit outside in sub zero temperatures, not on a charger, and the car battery pack has to warm itself to keep from freezing while you work for 12 hours?

The more I think about it, I suppose the vehicle will have to be positioned with wheels on four pods. Driver exits? A laser system then positions vehicle for removal of pack by automation. What if driver is about to pee in his pants after a trip, can he exit over the machinery? How long does the first act of positioning car take? Will all vehicles have universally configured pack and hook ups? How many of these complicated stations will one location have? Like I said earlier it is all about the logistics. Again, I'll take the two minutes at the gas pump.

Might be possible to swap out a replaceable battery pack faster than filling a tank with gas. The process would be fully automatic.
The pack would likely be swapped out beneath your EV.
As y'all are saying, the whole power grid infrastructure is going to have to be beefed up anyways; this would just be part of that.

EV will take a while to make a solid, reliable impact. Right now we have ****.

Except it doesn't work that way. You only have to charge enough to replace the miles you used that day. My Tesla charger in my garage adds @30 miles / hour. (And that is the Model X - others can add more) If I only drive 30 miles that day, I would only have to charge for 1 hour. I have a 200 AMP panel and am wired for 2 EV's with 2- 50 AMP breakers. Thus, my continual charge on both would be 80 AMPs. My charger is scheduled to start at 1:00 a.m. in the morning. Your 8 tons of AC combined probably use way less than 50 Amps - and typically are not "continuous". You could easily add 12x30 = 360 miles per day with one charger or double that with 2. Even with 4 BEVs you would be fine. You are correct that apartments etc have to up their game. The most recent apartment in my city has solar + electric charging for cars.
I am very fortunate. My first house built in the 80s had 100 amp service. How would I charge two cars over night? And apartments, condos, street Parker’s will be a problem. Maybe we won’t get to own cars, just auto driver everywhere. I am sure the poor people will be able to afford getting a new electric, or new battery pack on there Qi-we year Tesla that had the older battery chemistry. I am sure Tesla will ensure replacement pack availability...... oh wait they can’t supply repair parts now....

Nice to read lots of good creative ideas, information and feedback in this forum.
Yep, major infrastructure changes will happen. Not tomorrow, but maybe sooner than you might think.
I have reservations about self-driving cars until further technological advances occur.
But self-docking cars for battery replacement would be easy to implement. We already have parallel self-parking.
To accommodate the needs from small cars to large semis, maybe battery packs can be installed in a stackable arrangement depending on how many amp-hours are needed.

Regarding the risk of frozen battery packs, there is a similar problem with oil in ICE vehicles. In Alaska they have a heater attached to the oil pan to keep the oil and engine from getting too cold.
For EV, perhaps the vehicle's air conditioning system could be used, with the heat redirected to the batteries. Connect your car to home or service station power when doing this.
Battery packs naturally warm up in normal operation. They can get overheated due to external temperatures, or when there is a sustained high current draw (such as track racing). In the latter case, external air (preferred) and/or the vehicle a/c system can help cooling.
Battery packs may need a built-in array of cooling tubes to cool their innards.
