Proof that the widespread campaign against Toyota for not "going all in" on battery vehicles is fueled by ignorance

Toyota’s Chief Says Electric Vehicles Are Overhyped.

WSJ | Dec. 17, 2020: "In a country such as Japan that gets most of its electricity from burning coal and natural gas, EVs don’t help the environment, Mr. Toyoda said. “The more EVs we build, the worse carbon dioxide gets”

BATTERIES BATTERIES BATTERIES EVERYWHERE

Is not "green". Every single battery made today will die one day and need replacement. So when you plunk down $100,000+ for a brand new Tesla expect to replace the battery in 10-13 or so years REGARDLESS OF THE TOTAL MILES. And that's $15,000-$22,000 in today's dollars.

1. My experience (2022 Toyota Corolla hybrid)

Advertised as 50 (highway) 52 (city)

We regularly get 55-60, sometimes as much as 62 mpg on extended (100 mile +) drives thru mountains. 52-55 mpg on extended interstate drives. In other words, better than advertised. Yeah, I admit I drive it easier than some may…I kinda make a game of seeing how good I can do.

My only quibble with the OP is in the very last paragraph, and it is not specific to Tesla: It does not take into account the maintenance schedule of an ICE vehicle: oil changes, air filters, coolant changes, etc etc. Even brakes (because of regenerative braking your brakes last longer).

I am not claiming those items would add up to $15-20K in ten years, but I think it should be mentioned.

3. They are also make their projections based on current technology

I remember when the Prius first came out and people were saying that the main battery was going to need to be replaced in 100,000 miles at a cost of $10,000. I think current replacement from Toyota is at $2500 and there's a place locally that will put in a rebuilt battery for less than $1,000. I bought a used Prius and that battery lasted to 200,000 miles.

What about the next gen Tesla battery? What they call the million mile battery? Wear the car out and then use it as a home battery backup.

[Think. Again.]

2. ok, this really does make a lot of sense...

My gut reaction is to eliminate all CO2 engines as quickly a possible, but I also realize that lithium batteries, which are the state-of-the-art at the moment, will require serious ecologically damaging mining and are simply not sustainable due to lithium's limited quantities.

I'm pretty sure we'll eventually end up with hydrogen as the main vehicle fuel, either as a combustion fuel or an electricity storage medium for fuel cells in cars, or both, but we are not anywhere near that yet and need something to reduce fossil fuel use now.

Maybe this controlled and steady reduction method that Toyota is suggesting is the way to go at this point in time.
