Couple of other things left out of the original post:
DRLs; don't have 'em so traveled with the low beams on the whole trip, including in town. Have not done that since returning home and noticed a few instances of people "not seeing" (or ignoring) the smart so have gone back to using low beams all the time.
Speedometer is about 2-3 mph optimistic, based on my GPS readings. Of course, the GPS could be off also so I'll have to do a milepost check to really tell.
