I think this thread is about to become a lot more relevant in the near future. 1) Mass production of Model 3s is flooding California with Teslas. 2) Holiday traffic is coming soon.
I already got a taste of the waiting in line issue when I went to watch the recent SpaceX launch. Just before the event and just after I found myself arriving at superchargers at the same time as everyone else who was going to the same place at the same time.
At my first 'waiting in line' experience, I was first in line. Then 4-5 other cars got in line after me, but didn't quite line up sequentially. So I guess they had to memorize who was next. It was pretty easy to line up since there was a lot of space (San Luis Obispo), but apparently not everybody has the same concept of where the back of the line is supposed to be, or how the cars should be oriented. I would think they should be front to back rather than side by side, so that the whole line can move forward as chargers are freed up.
On my return trip, I was second in line and 3 more cars showed up behind me. There was no open space to form a line (Atascadero), so we had to randomly park in empty spaces and hope we could all remember who was ahead of who.
This can work OK when there's only 5 cars in line. But what will happen come late December and you have 15+ people in line? It's easy to imagine civility breaking down. We should plan ahead with a numbering system, perhaps.
What if some of us carry a post-it note pad and a sharpie? Then we can do a "take a number" system on the fly, and self-regulate despite the larger complexity.
Even if the people ahead of me don't want numbers, I could at least count the number of cars in line and give myself the next number. Then as more people arrive I could give them sequentially higher numbers. Who would refuse getting a number to assure their place in line?
The notes could be stuck to the windshield, perhaps, to make it more obvious. If it's raining, you could write the number on the back and stick it to the inside of the windshield
Any thoughts?
