No, it doesn't make up the deficit, it does end up slightly better than a ICE one after the projected life cycle of 12 years.
The problem is that unlike ICE cars Teslas are much less likely to be reused for 12 years, as far as other EVs go it's still an open question.
If the only two options are an ICE or an EV, it's likely better to have an EV despite the likelihood of PCO2E being underestimated in the supply chain especially when it comes to rare earths.
But if the option is to have an EV or no car and use public transportation or communal transport the latter is always better.
The ALH version of the Jetta TDI is a pretty good example. I personally owned two ICE vehicles that lasted well over 15 years and 250,000 miles. I have a 2017 Civic with 44,000 miles now. I average over 40 mpg even just driving around town. When we travel extended distances I can some times hit 45 mpg if traffic cooperates. The math behind the ICE vs electric isn't familiar to me, but I wouldn't be surprised if you're closer to right than most people want to admit. I do fully believe the math will slide greatly into the electric vehicle's favor eventually.
I drive a 2000 Civic with 205k miles (it was purchased used). It only gets about 25 mpg, likely because of a part failure in the fuel system that has been too expensive to fix.
I estimate 1000L (264gal) of fuel burned in it per year. That's about 755kg, and 35000 MJ (9800 kWh equivalent). The combustion produces about 2300 kg CO2. That's half the EPA estimate for "a typical passenger vehicle" [0]. An equivalent electric car likely uses less than 35 kWh/100 mi, so an all-electric power budget would be 2300 kWh, which at typical US power production is about 1400 kg CO2, about 60% my current footprint, on a strict operating basis. The battery represents about 5000 kg CO2, so it would be about 5.5 years until my "CO2 investment" pays itself off.
Given the current money-price differentials, and dearth of electrics in the used market where I always buy my cars, it doesn't make sense for me to replace my current car.
I'd also like to see a hybrid with a 20 kW I-2 free-piston linear alternator (probably from Toyota) before committing to battery-electric.
If anything, electric cars have the potential to last incredibly long. Combine with composite or aluminum body and the body won't rust away on an otherwise perfectly fine car.
Yeah, I'm confused as well. Generally in a 10+ year old car you're looking at possible transmissions issues(or engine depending on the brand, hello Subaru).
We're just about to crack 100k mi and 5 years on our EV with no sign of stopping. From a power train perspective swapping motors is dead simple and you have no transmission. I still see good capacity at ~91k. There are electronics/accessories that will fail but that's no different on an ICE.
Anecdata aside, the average car gets taken off the road around 11-12 years due to body rot, not drievtrain problems. EVs are unlikely to be immune to that.
There's still some decent physical shielding of the underside of the pack(which runs whole body). It'd be interesting to see the long term impacts that would have on the frame/etc.
