The truth is that in some areas, superchargers are already behind demand. Superchargers need to have more stalls than peak demand because charging is already slow compared to fueling up with gasoline. The time disparity is fine if there's no wait because it basically fills the need for most people's necessary occasional rest stops anyhow, but adding more wait would turn it into a negative experience.

I haven't yet had to wait for a supercharger, but I have seen full superchargers that I haven't needed to use. With the huge increase in vehicles from the 3's being sold, I expect congestion to increase before it's counteracted by more charging options.

I'll be pretty bummed the day I have to start waiting. Waiting might tip the scale for me from electric being a better roadtripping experience to gasoline. On the other hand, autopilot is pretty sweet.

I hope they don't fuck up supercharging like they've fucked up service. It's a necessary ingredient to a great overall experience.
