Is this incorrect?
You Jamie for pointing that out.
"Global sales totaled over 400,000 Leafs by March 2019"
That is awesome and the Leaf is a fantastic vehicle only limited by its range. But it does not sound like one million Nissan Leafs have been produced. And the Tesla milestone still carries extra significant because all of its models are reasonable replacements for ICEs in most households. The Leaf is suited to a much smaller set of use cases.
A Nissan Leaf is not as nice of a car as a Tesla Model 3 in pretty much any way, but it also costs 3/4 of the price. Meanwhile, the Leaf is profitable per-car, and the base model Tesla Model 3 is barely break-even per-car, even with the very aggressive accounting that Tesla uses. Tesla can't keep producing base Model 3's at the price they are selling them for (even at over $40k), they are a loss leader to look competitive on price, the profitable version is well over $50k without government subsidies that will end this year (and the performance model is over $60k). A leaf is around $30k.
GM had a great electric car in the mid 90s that couldn't compete due to lead acid batteries being heavy and having poor energy density (https://en.wikipedia.org/wiki/General_Motors_EV1). Put Lithium batteries in an EV1 and people still wouldn't have wanted it because oil prices were low, but it beat the Model S to market by nearly 20 years and again given a better battery technology like lithium would probably have led to a majority of cars being electric today.
The tide seems to have turned... a bit.
Have improved emission standards done more to comeback air pollution that Telsa?
I’m no expert, but I’m willing to bet: yes.
Will has improved emission standards always out compete electric vehicles? I’m willing to bet: no.
We definitely want to improve ICE engines too.
With any new technology, the real trick is to produce a marketable product then keep iterating, with customers providing the revenue.
Big LCD TV’s, for example, used to cost over $10,000.
Now that Tesla has proven the product, we are now getting a battery arms race...
Anyway, this is all well known about how technology works... Apple I to iPhone...
Now where are consumer robots?
There's no urgency for Toyota to produce electric cars because they've been making hybrids for a long time and they're already in a good position with the new emissions standards.
