I've been misinformed. Sure, you don't need the monthly plan, but at least one of the DCFC purveyors would charge you $.50/kWh without one. Or, only (from memory) $.25/kWh if you paid (again, from memory) a monthly sum of around $20.No subscriptions needed for either. Could also tap your phone to activate the charger too. It's definitely less convenient than Tesla SC, no arguing that, but it's not as bad as people make it out to be.
As for road trips, I think it depends on where you are going. It's the same reason that people want CCS adapters and the Chademo has a reason to exist. Generally the SC network is much better but there are places with DCFC without Tesla chargers.
I returned that lease back in 2019, but at that point the DCFC chargers were often empty while Superchargers were packed. It's gotten better since then for Supercharger access, at least here in the Bay Area.
Let's look at economics: How much does 50kWh cost at the DCFC non-Tesla stations? What percent of non-Tesla DCFC are more than 150kW? Include any facts like if price quoted is for any Joe with a credit card that drives up.
Not directed at you @Cheburashka, but answers to these questions may be salient to EV adoption. And, IMO, Tesla charges way too much for Supercharging during the day. I understand why they do it, and it does mitigate station traffic during peak charge hours. Off peak hours around SoCal seem to be as low as $.21/kWh in select Supercharger stations. Again, it would be fascinating for an apples-apples comparison.
For those without home charging who rely on DCFC, total cost of ownership needs to be factored in. May the cheapest purveyor win.
