You must be able to go to sleep really easily to be able to sleep while charging and not stop otherwise but 8 hours of sleep on the 73 hour trip seems dangerous to me. Yep, have to agree @outdoors Coast to Coast makes more sense.
Although I still think it might be a good idea to leave from Victoria.
Minor adjustments. Ok 4 days then. Yes mile zero for sure in Victoria. Yes I do I have a technique for rapid sleeping. In other threads I am able to drive a thousand miles a day pretty easily. Model 3 actually might not change anything for me. It boils down to rest on a trip like this not supercharging speed. So faster charging might not benefit me as much as I might need more than 16 minutes of sleep at a supercharger. So I charger higher, drive longer. Sleep a little longer.
