On the trip there, alone. On the trip back (Lex-Nashville) myself and 3 passengers and luggage (nothing heavy, 2 smaller kids and wife, probably total 480 lbs including all passengers and luggage. It was in a 2 week old P85D, with a Chademo adaptor along for the ride just in case (but not used). There are at least 2 Chademos on the northern outskirts of Nashville where I could have charged if necessary.
If memory serves, I still had almost 30 miles left when I arrived at Brentwood. Max charged when leaving Meijer in Lexington, kept the car in range mode, drove at a careful but comfortable speed on a beautiful, cool Sunday morning. I typically drive a couple of mph faster than everyone else on the road, so I wasn't going slowly.
