Everybody keeps talking about miles, but EVs aren’t about that. Age matters for a battery more than miles. After about ten years you’ll start seeing a steep decline in battery performance as individual cells get weak.
No. It’s the number of charge cycles. Basic chemistry. Today’s technology is good for enough charge cycles with good battery management software to go 400,000 miles.
Well, several automakers have announced plans to move to EVs by this time anyway, so it's not as radical as it may sound at first. 34 years is also quite a long time - think back 34 years ago to 1986, which was prior to the advent of the world wide web and cell phones as we know them, that's how long it is, in tech terms. EVs, and their infrastructure, can make a LOT of progress in that time.

Not with solid state batteries. They last the life of the car. By the time EVs are mass take up, solid state will be the norm.

It’s about age too. They will get weaker with ago no matter the number of charge cycles.

Even back in 2005 in my freshman physics class we had a debate about whether or not the future of cars was hydrogen fuel cell or EV. At the time, batteries were a far cry from what they are today, and there had been some headway in fuel cell development. Some larger vehicles like buses and delivery vehicles which ran local routes and returned to a depot where they could be fueled up each night offered hope that the technology could be improved to to the point that it could be applied to consumer vehicles. EVs were largely concepts at this point and we were only on the first round of hybrids which provided supplemental power to ICEs.
That was 16 years ago, not much longer than the gap between 2021-2035. The Tesla Roadster (basically a rich person's toy) was only 3 years out and the Model S only 5 years out. Things have certainly changed a lot since then (we're not talking about hydrogen powered vehicles anymore) and they'll continue to do so over the next 14 years.

It's mostly charge cycles and the settings for that charge cycle, though even there it appears the number of miles/charge cycles appears to be dominant in real world conditions as I recall from an Idaho National Laboratory paper on this. Most formulations of lithium-ion batteries aren't going to show much any real degradation if you just kept them locked up in a room temperature environment for a decade and never charge or discharge them. There's not going to be much of anything in regards to degradation from just sitting doing nothing except for the one cycle of self-discharge over the period of time. Where are you finding this information and the mechanism for loss of capacity over time without any charge cycles? I'd be curious to read about it as it doesn't seem to make sense given how secondary cells usually work.
Too cheap. It you pollute the valuable air we breath you must pay heavily. We have no choice what air to breath.
You would hate living here when the forestry service does their winter controlled burns. It makes what comes out of a car’s tailpipe seem like gnat fart.

Two wrongs do not make a right.
