One problem they haven't solved is range. My little C55 may not be as fast as a Plaid but I was able to drive it NYC to Dallas in a day and a half. 1700 miles in a weekend is a bit of a stretch for an EV.
I am guessing with a new Tesla that you would have spent two to three hours charging on that trip.
The overall impact could be less if meals, rest stops and lodging was coordinated with charging.
I don't think there is any doubt that to minimize the time needed for an over the road trip with an electric car requires planning.
