Even though modern gasoline especially in California burns quite clean, it's easy to forget that every bus and truck out there is burning horrendous diesel.
I was in the New York Port Authority Bus Terminal for a few hours the other day and it just felt toxic, I felt so bad for people who spend time there every single work day of their lives.
Let alone the vast majority of the world's population whose streets are completely choked up with buses and completely dirty fuels. It'll take a while but you're right this is going to seriously change lives at grand scale.
The NY MTA has been running natural gas buses and hybrid-electric buses since before Tesla was a twinkle in its original founders' eyes. It hasn't fully converted it's entire fleet yet (the process began in 2000!) but it's one of the largest alternative fuel fleets in the world.
LA Metro's fleet has been almost 90% clean air for years, and has been testing EV buses for almost a decade.
Let's give Tesla some credit for making EVs fashionable, but public transit systems have been going green for much longer and Tesla's never been part of that conversation.
I am saying there is a huge bias for news that is they are going bankrupt, they are killing people, they are going to destroy all other car companies.. etc. because that is what gets the clicks.
Ars technica even has an article about sudden EV-charging power demand may force electricity company to fire up coal-plants for the load, which causes even more pollution. If they have a set schedule and not cause a shock load, then the power company can stick with more of the renewables.
It isn't the silver bullet that everyone claims it to be - don't look too hard at the manufacturing either.
