Not impossible but much harder than working closely with humble and experienced engineers. That's why I recommend that a junior engineer finds a great consulting company as soon as they can and spend a few years there. This was a kinda breakthrough period in my career for both technical and soft skills. The nature of consulting also means that you might see a greater variety of environments, technologies, and problem/solution combinations than the equivalent xp in a non-consulting role. But make no mistake, finding a "good" consulting company is key. You need to have humble and experienced engineers who want to help you and grow you. If it's a "bums in seats" kinda "body shop" or some kind of celebrity house for "hero" or "10x devs" then maybe this won't be as useful.
you just need to know the SoH (state of health). If that's 90% then you've lost 10% of the range at new. The lower the SoH for the same vehicle make, model, year and driven kms, then the worse the car has been treated. Simple as that.
I don't understand where this thinking comes from. It's not based in fact. These Tesla batteries degrade very slowly. And so if in 5 years you've lost 15% of the range, it still gets you anywhere you need to go including road trips with all of the Superchargers!? "totals the vehicle" is just nonsense and I wish more people understood the reality.
