Are they not still dependent on selling credit (which the government requires people to buy to offset environmental impact)?
Not really. Last quarter for example, they had $14.6 billion in automotive revenues of which $344 million was regulatory credits or a little more than 2%. They had $4.1 billion in automotive gross profits so regulatory credits made up about 8% of their profits.
Meh. Amazon ran for 20 years before posting a profit.
