Unless you find food made without fertilizer that result in NOX emissions then the Tesla won't help with this particular problem.
Just like going from combustion engines to electric vehicles will require major infrastructure changes, as will going from modern industrial farming practices to climate neutral ones require large changes in the way we produce, consume and think about food. You're not just going to be able to tell farmers to stop using fertilizers without a viable alternative.
Your case would be rather stronger if you didn't drive at all. And ate only vegetables from local fields farmed organically. And never took hot showers. And powered all of your electronics exclusively through wind and solar. And never connected to any servers or over network links that were not sustainably powered.
You seem to be radically underestimating the scale of the problem. Being fortunate enough to be in the set rich enough to afford a luxury electric car absolves you from nothing.
I'm going to assume that was supposed to be sarcasm and it is a) going over people's head and b) being willfully misinterpreted because it hits too close to home.
How did you produce your wealth that let you buy your Tesla? Accounting for that, is your ecological footprint still smaller than that of a working class person driving a 1995 Honda Civic?
