carbon credit: EU law fines ICE car makers for making cars. they inturn purchase carbon credits to have the right to keep polluting. further more tesla made 53 B$ in rev for 2021. 1.5B is not nothing but not > 5% of revenue for the year. ie bulk of it came from actually making and selling cars.
tax credit: the US federal govt had a tax credit program which was lobbied by GM in the 2010's that gave car buyers 7.5K as a tax write off . this was only eligible for less than 100k cars sold (tesla sold 405,300 in q4 2022) and was only useful if you made enough income where a tax writeoff made sense. 2023 new laws are in place with more rules which makes them almost useless (or only useful for those who lobbied for it).
I'm still young, but hearing about this kind of feature makes me feel like a luddite. I just don't get it. Is it so passengers can play while you're driving, or just to play while the car is charging/you're waiting somewhere?
It's pretty neat. It's really cool to go car camping and effectively have a portable mini-theater come with you.
