There are not many of us in the 30k+ miles club
I only know of about 6 including myself. But one of those I think had 35k or 40k already. If I recall him and his wife split usage (drops him off at work then does her daily thing then picks him up etc etc something like that), and they travel something like 300 miles daily. They use the supercharger not once, but twice daily. It was on these forums somewhere...
I myself drive 210 miles daily and I can't make it round trip on a single charge. I charge at home to 80% which is about 200 rated miles and drive 100 miles to work leaving me at 15-60 rated left. This uses anywhere from 38-50kW and varies depending on traffic, speed, weather, and heat. and I drive fast. Btw yes those number are right, I've used up to 50kW go 100 miles (500kW/mile avg) a few times (and that's not even counting charging efficiency from the wall). So technically it pulls up close to 60kW sometimes.
When I reach my garage in the city I then plug in on a charge point and charge back up to 80% and repeat the 100 mile trek back home. . So I do charge at home and at a parking garage in the city. I try to keep it within the 80% -> 20% range always. I basically do a little more than two half cycles daily.
But there is a supercharger about to go under construction on my route. I use about 2500kW per month for the car alone with all the mileage I do and we do not have discount rates like you guys got out there in CA. So there's a very likely chance I might switch to SCing daily if it saves me about $350-$425/month in electricity. I wouldn't 100% charge solely there and not charge anywhere else (not talking about range charge, but amount of time spent charging at home vs SC). I'd probably calculate and time the charges in a way that I'd stop there once daily to charge from 15-85% and be on my way. Aka do something like schedule a charge at 40A and hour before I leave which would be enough to get me to the SC - in other words structure it in a way to maximize the free electrons while still keeping the battery somewhat around that safe zone (non-extremities). I'd probably park somewhere cheaper too if I don't need to charge at the garage anymore. Anywho the exact details of all that I would need to run but the point being is that I might consider doing this daily to save a few hundred bucks a month.
AFA it's effect on battery , all my research and even comments from Tesla employees and managers say that supercharging is the worst thing you could do for your battery outside of bricking it by leaving it dead or damaging it by leaving it at 100% in scorched weather. But Tesla's "official" word is that it's safe and the battery is warrantied and not to worry about it soooo the jury's still out on that one. Who knows.
I realize opinions on this will be very subjective. Some would say I could just continue what I'm doing now and not use the SC. Others would say "hey, we paid for it". Some might say "it's all free energy anyway so who cares?" (Assuming of course Tesla builds all those solar arrays). But who draws the line? Is there a specific mile have amount that warrants it being 'ok'? Or is it the purpose of your trip? Weekend leisure travel vs daily commute? Inter city driving vs "it's on the way home"? What if your like me and its a daily commute but it's far as hell and honestly I go past several cities daily? lol.
IMO there are no clear day and night rules here. The other thing to consider is that these superchargers on the easy coast go mostly unused unlike CA. The only competition we have out here for the supercharger spots is against a-hole ICE vehicles hogging the spots because they are too lazy to walk 10 feet further
(and that IS a problem out here, and there have been a few very close road rage/fist fight incidents with these ICE drivers bc of that). While CA superchargers , well specific ones, seem to be used 24/7 I can see how a daily commuter would annoy travelers if all the spots are always taken. But for the time being that's going to take another year or so out here to get up to those levels...
