Despite probably not having the senate, Tesla will still gain a more positive environment under a potential Biden Presidency:
- A Biden administration will control an EPA that supports states clean air standards for vehicles (unlike the current administration that is fighting States in court)
- America will likely rejoin the Paris Climate Agreement
- Their still exists the chance that a republican senate supports an EV credit extension, not for teslas sake - but due to the fact GM also doesn't have access either, and at some point even Ford will run out and it will only be foreign manufactures selling EVs that have access to it and no US politician will want that. Worth noting Texas Senators now have a reason to support EV tax credits for Tesla due to the new Austin factory Jobs.
- Biden has a green jobs agenda, and commands the vast resources of the federal government to make the environment better through regulations & executive orders for green tech companies like Tesla, despite not having control of senate. For example I wouldn't be surprised to see some sort of mandate that new federal vehicle fleets must increasingly be EVs.
