I think you are worried about nothing. Here is a screen shot of the number of Superchargers being built right now from
supercharge.info
View attachment 951885
Will follow up with:
Current V3 + under construction circa June 2023
Current V3 + under construction circa June 2023 with 20+ or more stalls
Current V3 + under construction circa June 2023 with 40+ or more stalls
So a 25% increase in superchargers planned/in-progress. Point still stands, availability is still lacking in parts of country + anecdotally on a recent drive down to LA a lot of chargers are at 100% capacity with in-nav quoting 25min waits.
Interesting to also note the largest concentration of 'large' SCs [read: 20+ stalls] are in CA, and southern CA to be specific. Suspect Tesla sees the same thing.
Will older bolt/leaf give access to supercharger too? Even though they shouldn't there ARE cars that charge slow af and could squat on spots. I'm sure other companies will be ramping production too soon.
I do not know either way but my
guess is "no". Would also hazard a guess that DC quick charging will become a standard feature on mostly all (if not all) EVs going forward.
People have been asking this for years and speculating about massive problems.
It’s never been a significant issue. No reason to think it will be any time soon. Tesla makes more EVs than every other manufacturer combined - at this moment in time giving other vehicles supercharger access is a tiny drop in the bucket.
Did not initially click how much SC demand originated from Tesla itself - and to Tesla's credit - their ability to match increasing supply to increasing demand appears to be working.
I do think one thing which caught Tesla offsides is a higher than expected uptake to use SCers as a regular charge option, particularly with the 3s/Ys who domicile in an apartment, condo, or some other urban-ish setting where adding L2/L1 charging is not practical...if you want to see one busy-a$$ supercharger, check out the one on W Alabama in Houston TX...insane utilization till 1/2am!
This location supports a urban area in Houston with moderate residential density (e.g. mid-rise apartments/condos and patio homes) and while the patio/SF residences presumably could install a feasible L2 solution, I'd assume less options exist, if any, for the apartments and condos...hence the demand rebounds to a swamped SC location.
That said, Tesla's brining online two new locations / 24 stalls combined in close proximity and one hopes the boost in supply will help ameliorate the high usage at W Alabama. To the larger point though this does seem Tesla's aggressively moving to build out excess capacity where needed, even if it's a tad late due to unforeseen demand from those who cannot access a ongoing L2 solution when Tesla perhaps thought they could originally.
