Thing is, i am not point out like they are investing 'knowledge' into the sport like that brings them forward, i'm talking about their dollars and name.
Tesla can simply 'badge' batteries with Tesla. It's essentially what's been written above. I know fully well that Tesla's wall battery for example consists of nothing but panasonic or 18650 cells with a Tesla label on it, packed together, and a pricetag of 9000 USD whilst you can make the same pack yourself for about 800 USD.
thing is, i think Tesla could do with F1 as even more exposure and attention and invest. For example, Tag Heuer branded Renault engines, even if that's to work around the renault discomfort, Tag Heuer gets great exposure despite there is literally zero connection between Renault and Tag Heuer. I think Tesla in F1 - solely as sponsorship/branding - is 'just' a matter of time.
Dumpster sounds so much more classy. It's the diamond of the cesspools.
