You had me until that last statement. I'll drive a mile out of the way to avoid a traffic circle, roundabout or glorieta.
There was one on my route (the intersection of RT 206, 202 and 28 in New Jersey). After three near misses in a row from mooks who didn't plan ahead and get in the correct lane, and cut across lanes to make an exit or continue around, I avoided that abortion for two years until I moved elsewhere. I'll take traffic lights any time.That's maybe because you're not used to them and have to share the road with other users who are not used to them
Think about the queues you see at the intersection of two six lanes highways (plus the turn lanes) and you have to wait for the cross traffic, then the left-turn cross traffic, then your left-turning traffic, then you get to go (and in Dallas, there's ALWAYS some a-hole who makes the left turn AFTER his arrow has turned red)  ... and you can't be certain which comes first, turning, or straight ahead, or some even do turning, then straight ahead, then turning again. And don't even bother when there's a power cut or a rainstorm and they all go to flashing red and the tailback is three times as long
A roundabout is just constant movement. You only have to look in one direction and it never gets affected by powercuts
 and how often have you been blocked from even getting into the left turn feeder land because there are so many peeps going straight ahead?
I'm not sure I understand this. Can we have more details? What is the actual distance traveled? Are there any major elevation changes? 6 hours at 75mph (although maybe you drive much faster--would be interesting to see if by just slowing down a bit you could avoid a stop) is 450 miles.I did a trip from CA to AZ, which can be reached within 6 hours. But with the Tesla I had to charge 3 times, and I believe it added an hour to the commute just to charge and not able to drive. My friend started to get annoyed about having to stop every 2 hours because he drives a fuel efficient gas car, a Toyota Camry, which he claims he can drive 400 actual miles. He said he just need to fill up once and that be enough.
Stopping 3 times does suck, but then autopilot makes the car much easier to drive long distance. Gas cars even if you save time not super charging, you need alot more energy if you don't want to stop at all, and there is no autopilot to help out.
You talking about like state highways with twin carriageways?Maybe other states have something similar, but maybe it's a uniquely Texas thing like Jug Handles in New Jersey, but ... apparently the U turn lanes at junctions with separated grades are called Texas U Turns ... and it's surprising how often they get used
Efficient, but still not as efficient as roundabouts
Never occurred to me that I hadn't noticed these in other states. As a matter of fact, I use that very turnaround once a week or so. Handy as a pocket on a shirt. Sometimes blending in to the left lane with traffic coming from the right can get a little dicey, but all you have to do is wait for the light to your right to change, and don't faff around making up your mind.It's when you can go from the Northbound service road to the Southbound service road without entering the cross street
Maybe a picture says it better - See how you can go from the Northbound service road of US75 round the Texas U-turn to the Southbound without getting onto Lovers Lane. No lights
