Just got back from a 4000 miles trip from Florida to Quebec with 4 kids, my wife and her quide dog. Stopped in DC for 2 days to see the wonderful musium, walker around the Liberty statue to break the trip on the way up. Came back through Niagara Falls, Ruby's falls, and a big sink hole in Gainsville.
Charged 13 times on the way up and ? On the way back with no problems. Had to adjust my spread a few times and ignore the car asking me to turn around at a few times... Closest call was with 15 miles range left... My wife was a bit worried... At one of the station 2 cop cars stopped to see what type of car it was:) no ticket.
The cars seems to assume you have an ez pass so you have to be carefull when following the GPS. (we have sun-pass in Florida and they are not all compatible:( just got a bill in the mail...
While I was in Quebec there was an update that changed how the car react around semi probably in reaction to the accident what was just reported. I have to admit I do not like that update, it makes the car unpredictable around big truck. One time the autopilot did a lane change between two trucks I really wasn't expecting it. The car also some times slows down while passing them, could be a problem if someone is following you closely and very annoying.
Overall loved the trip, auto pilot makes a world of a difference. Not as stressful, more relax you just have to be aware of your suranding and be ready to take controls.
