Pretty short sighted of the GM ( and the other manufacturers ) to go all in on electric vehicles.
The power gird is aging, there are warnings that come out during the summer all over the US and a number of the larger centres in Canada that "Peak Demand" has exceeded last years record, and brown outs and system failures, having to import power from other places, use your oven/stove after 7pm etc etc etc.
Now, add everyone plugging in their vehicles at 1630-1700 every night just as your AC is raging, or in the winter when your electric baseboards are firing up and drawing another 80 to 200 amps all night long. It's fine for now with minimal EV's but in a few years, where most families have 2 or 3 vehicles and WOW !
Was your present neighbourhood built with that kind of electrical infrastructure?
Mine was built in the late 70's and ,,,,,,,,,,,,,,,,, NO it wasn't.
My home was built in 1978 with baseboard electric, I swapped to Fujitsu MiniSplits about 8 months before buying the Tesla. Believe the transformer is shared with just one neighbor, car is set to charge at 1am in summer when load is low and 4am in winter so the battery is warm when I leave for work. I charge it at 60amps this time of year. Voltage sag is about 5volts from 243 to 238 and that is while the water heater is recovering from my shower and the wife is up making coffee and the minisplits run pretty regularly. This is a very reasonable level of voltage sag, utilities don't care till that number hits 10%. Neighbor has a large hot tub and they and the teenagers aren't shy about leaving everything turned on.
Getting rid of the baseboard heat is what bought me the capacity, and I think why the infrastructure is so good.
Some aftermarket charging equipment can be remote accessed by utilities in order to help manage loading, often those are free from the utility. The Tesla charging equipment is set up for random staggered restarting if there is an outage that interrupts or anything to help soften grid load. I am not some sycophant, I enjoy the car, I think it is a better option than most like yourself are willing to admit. I think that with smart management of charging the grid has a fair bit of capacity in much of the country, obviously some areas have been grossly mismanaged and had issues even before EVs were a thing. I couldn't say if the current grid can handle 5% EVs or 10% or anything but I will agree it wont support a mass replacement of gas anytime in the next decade or two. Gas cars will be around a long time. I think the states and countries looking to ban gas car sales by 2040 are idiotic. Liberal feelgood stupidity from Democrats that are just "too smart to connect with voters" or maybe just too stupid to realize they are stupid.
The grid is not setup to handle that kind of demand and electricity generation causes pollution of various flavors as well.
Coal, Natural Gas, Hydro, Wind, and Solar... All of them have serious but differing environmental impacts.
I can see another possible downside... Once the nation has been moved over to electric vehicles electricity "shortages" from pollution regulations will be used to control the mobility of the population. Don't believe it? Wait.
EVs definitely still cause pollution from power generation, BUT the controls are that are easier to manage at one central location than on millions of separate cars in various states of neglect. They can also be miles outside the congested city diffusing the pollution which is China's big push. They want EVs but not because they are clean because they can spread the pollution around and be less devastating in the cities.
As EV ownership grows battery packs salvaged from wrecks or will wear out to a point where they are not good for transportation or anymore BUT maybe still function at 50-70% original capacity, I think you will see those recycled as home energy storage coupled with more solar. Even without solar home storage or bulk storage by utilities to save excess capacity when it exists and even out the load. At this point the Tesla power wall(battery to help with time of use management) is insane to buy unless in an outrageously expensive utility area with aggressive time of use pricing but the idea is sound.
As I said above charging at low times of use can make use of the grid we have, and there are options that can throttle or stop use if load is too high. It isn't enough to replace any significant portion of the gas cars on the road, I believe the average age of cars on the road in the USA is like 12years so even if something miraculous happened and EV sales spiked to 10% of new it would be a long time before they began offsetting a volume of the cars on the road.
Gas will spike again surprised it hasn't, weak leadership in Europe and the USA in the past and in most places in the present has emboldened Russia, Iran, and China militarily. When some crap hits the fan gas will spike, electricity is more stable in price, less manipulated. Yes prices will rise with demand at some point but to suggest it will be worse than what happens with gas prices is IMO not a defensible position. Yes we have had it good for awhile but something will happen.
I might have said it earlier, I think I save something on fuel vs. the LS3 car this replaced(17mpg on premium), in summer I think I save a fair amount, in winter not so much, don't think it cost more but isn't saving what it does in summer, but whatever it is it in no way justifies the purchase of such a car. End of the year I suspect a 4cylinder midsize or below car that gets mid-30s or better would be cheaper on "fuel". Winter battery and cabin heating drastically increase energy use vs. the other three seasons. Impala being half as much to insure and OK but not great on gas would be cheaper at the end of the year insurance/gas wise. I don't have numbers to back that up but the "published data" suggests a model S should cost I think it was 1/4-1/3rd as much to fuel as a 25mpg car at $2.69/gallon but that was just based on published efficiency which takes a beating in winter and gas has fallen below that. In January the car will report double energy use with my short commute and sub-zero weather, but that does not take into account the energy used from the house while plugged in just what is used from the battery while driving. Things like warming the battery before charging and the morning preheat of the cabin are not reflected and I believe take a big bite out of my theoretical savings. I don't care enough to actually meter what goes thru the wall connector.
