If someone can propose a better idea I'd like to hear it. You can go further on 100% but the time you waste charging probably won't be worth it. I'd be curious to see a realistic scenario. Maybe they can install a couple destination chargers at the congested superchargers for people who want to charge from 80%-100%.You can definitely make it further driving slowly on a 100% charge than driving slowly on an 80% charge. Not everyone is making the same trip up 395 that you are. Your idea is simply a bad one.
Next time I'm definitely going to consider taking my 17mpg rig if the situation on the 395 doesn't improve.
