Picked up my wife's Model Y LR yesterday. Had to drive to Chicago to get it and went through a whole check sheet of things to make sure were ok. Everything was fine and the whole ordeal took less than an hour.
It was charged to 85% when left and I had to stop in Davenport one time for 23 minutes at a supercharger, and didn't stop again. In those 23 minutes, I probably spent 15 walking to Kwik Star, bathroom, buying snacks, etc. and the last 8 minutes fooling around with the new car. It told me that I only needed to charge to a certain amount but I went 10% over that just to be safe. I could see taking it somewhere like KC but I'd go with the Kia for anything longer. I think 260 miles ended up costing me around $11. So if gas prices are $3.60/gallon I think that comes to about 85mpg, which isn't too bad at 80mph speeds. Tesla costs were .34 KwH and my home will be around .11 KwH.
The autopilot (didn't pay $15k for FSD) worked fine but I discovered something that probably won't happen again but was good to find out. I had AP set on 82 and I accelerated past 85 to get ahead of a semi. Apparently, Tesla AP has some kind of rule that you can't use AP above 85 and it locked me out of AP (not cruise) for the final 30 miles of my trip. No big deal and good to know.
Now for one down side. We are about 10 days from installing our Tesla charger at home. Until then, I'm using a wall plug which means we get about 2% charge per hour
