So if you are starting the day with 95% charge, and ending the day plugged in at your destination with 15% charge, that means you can travel about 450 miles with just one ~20 minute stop to charge along the way.
How is that not fast enough? The only issue is if you can't plug in at your destination. Maybe in that case you have breakfast near the next Supercharge on your route.
Yes, it is something you might have to think about for a minute. The guidance software will map out Supercharging stops for you.
I do expect that they will figure out a reservation system which tracks and queues vehicles en route, like an air traffic controller, to cut down on inefficient ad hoc queueing at the location.
It would be super fun to program such a system, backend and front. Even more so as the cars become increasingly autonomous.
For now at least you can click on the map and see live how many chargers are in use.
With V3 Supercharging, you can drop in with your Model 3 at 15% and be at 80% in 24 minutes. In my road trip experience, that's barely enough time for everyone to use the bathroom and pick out a beverage. [2]
