Please wait...
I am more worried that "they" will force us to use public transportation for everything.
Tesla was trying to develop a battery changing station, where you don't have to wait for an electric car to recharge you replace the battery when you need a recharge.
Batteries die for no reason. I've got electronics that are garbage because of their non-replacable batteries.
No thanks.
What is "MPGe" and how is it calculated? Do they actually not count mileage that was achieved from a plug-in charge? That seems *very* disingenuous, especially if the fuel efficiency targets are ostensibly intended to minimize emissions, in a world where the plug-in charge probably came from hydrocarbon fuel anyway.

If they did, I think they abandoned the concept early on. The batteries are huge, and built into the floor of the chassis. They have their own cooling system built still have an unfortunate tendency that, once they catch fire, they're rather hard to put out. So I don't think the batteries are going to be removable any time soon.
I don't know how MPGe is calculated. I do know that that vehicle gets 30mpg, combined, if you never plug it in, and 71 MPGe's, whatever those are, if you plug it in.

Yes they did abandon it, you can watch the prototype video here:

Seems disingenuous to me, but my brain is wired for engineering. I'm still annoyed that light bulbs are still sold according to their "equivalent incandescent wattage". Learn what lumens are, people!
Seems legit; looks like MPGe is a pretty basic conversion to kwh/mi based on the typical thermal energy in a gallon of gas. Not sure if the assumption is exactly the standard value for gasoline, but it's close, if it's a little off it seems slightly biased towards *gas*
It's wall-socket-to-miles and doesn't account for upstream effects. I also found this: https://www.ucsusa.org/clean-vehicles/electric-vehicles/ev-emissions-tool
And of course that only satisfies people who care more about emissions than about the TCO of the vehicle.
Honestly, I *do* expect to own an electric vehicle someday. I just hate the idea of being railroaded into it before the technology is truly ready.
Work being done on supercapacitor substrates looks way more promising than the current practice of filling the car up with Lithium batteries.

That's nadia at work
They really should have left the self-driving thing out of it, though. I am skeptical that self-driving cars will take over.
Then they got into "climate change". That's something I'm *not* skeptical about; I am on the side of science, reality, and common sense, and am 100.000% convinced that the CO2 generated by burning hydrocarbons is NOT causing a runaway greenhouse effect.
Right now, it feels like one would want both kinds of cars. That's not practical for most people, but I could easily see a transitional era where many households have one gas and one electric, and if someone is going on a long trip they take the gas powered car. Right now I'm thinking I'll keep my 20 MPG pickup truck for the "real work" long after I've started driving a zippy little electric around town.
And I'm still wondering why they aren't putting solar panels on the roofs.
Autonomous driving vehicles would work if EVERY vehicle was autonomous and communicating with the other vehicles. We could be transported at much higher speeds if the infrastructure was in place.
I enjoy driving, I am looking forward to autonomous vehicles.
My neighbor has solar panels on his roof, they are difficult to see during the winter months but they are there. I have seen many solar farms driving around.

IG - Are you saying that you wonder why they aren't putting solar
panels on the roof of cars or the roof of buildings?
Cars. So what if the surface area is small? Many vehicles will spend more time sitting parked outside than being driven.

Electric vehicles will become a day-to-day reality someday. But this day is not today nor tomorrow.
Electric cars are fed by power generated by a mix of renewable sources and fossile fuels. In some nations it is more ecological to use electric cars because they renewable to "bad" fuels is good. For a lot of other nations, it is not. I think a whole lot of the push for electric cars we are seeing is due to political lobbying than actual advantages of the tech. I mean, if the tech was already there, everybody would already be buying it.
And yes, I have already been outpriced and forced into collective transport for many of my trips. Which is NOT a bad thing. I save money and I burn less fuel on the trip. Also, parking (having a garage or parking spot) is getting crazy expensive around here so my car does not see many trips.
You see Tesla's every day around here. Great city car apparently. Horrible for my lifestyle which includs a 8-10 hours on the interstate every winter weekend.
An interesting question is whether the developing world can afford this stuff. Probably not; I spent a month in India and much of my travel was by motorbike or autorickshaw. The latter are all powered by two-stroke motors that belch oil smoke constantly. If nobody can afford a cleaner-burning gasoline engine, nobody can afford lithium-ion.
