I'd like to say that it went fine, but along the way the car started behaving weird which is why I got an alignment and balance after I got to my destination. There's still something weird with my car where it doesn't feel planted on the road, so I've set up an appointment at Nashville for my trip back to VA.
Apart from that...
Stopping to charge is actually very nice. Charging stops aren't long, maybe like 15 mins or so, then drive for an hour and a half. It's a nice little break instead of driving for 2-2.5 hours straight (though I've done that as well, which feels much more tiring). During my first day, near Chattanooga, TN the car estimated that it would take me an hour to travel 15 miles and get to the city. I thought that didn't make any sense, then it turned out that there was a big traffic jam due to an accident. It looked pretty nasty. Fortunately stop and go traffic is the best use of an electric vehicle's single-pedal driving, and I didn't fear running out or battery because idling with AC uses up maybe like 1% battery per hour.
In Knoxville, navigation routed me *through* the city to avoid the traffic jams in the city's highways. Ended up going through a random tunnel that only has space for one lane. In one of those TN cities I briefly missed my entrance to the highway, so I went through a back road and passed next to a pretty futuristic pick up truck (I think it was a Toyota?)
Another memorable part of the trip was the Lousiana bridge between Lafayette and Baton Rouge. I thought it felt endless. Looked it up when I got home, and turns out it's 18 miles long and the 3rd longest bridge in the US. It's the Atchafalaya Basin Bridge.
Got lost finding the supercharger in Lake Charles, Louisiana, and navigation briefly took my car "off-road." I probably should have done a u-turn and returned the way I came - it was very eerie driving with almost no traction control or regen braking, so I had to slam the brakes a couple of times.
My third day was not too memorable. There's just not much going on from East TX to deep south TX. There was one spot where my headlights activated, and I saw a deer on the side of the highway. Passed a bunch of work vehicles going into local ranches.
On my way back, my first day will be all in TX, which I think will be very boring. I'll pass through San antonio and Austin and circle around Dallas, then spend that night in Texarkana. Then the next day I'll head up to Nashville and spend two nights there. The morning after my first night I'll drop off my car at the Tesla service center in Nashville. Hopefully it gets fixed by the end of the (business) days. Then I'll attend a concert for a Korean pop group that night, and head back to VA the next morning. This is all assuming I don't run into issues or flat tires or anything
