My best is 60.0 I use slippery mode. My 53 mile commute is about 3 miles city, 15 miles back country road at 50 MPH and the rest highway where I set cruise control at 59. If you set cruise higher than that it stays mostly in gas mode.
I could never go with stubby as I like to listen to sports while driving. I would really be ticked off if they take AM radios out of new vehicles like I have heard is a near future possibility
They could translate it, besides all of our street signs are English. You have to know some English to survive. As far as I know there is no translation services to decipher drawings. Obviously everyone can't understand a picture or we wouldn't be having this conversation
The dealer should return your vehicle the way you dropped it off to them. If you had decals applied to the exterior and they complimentary washed it and decals came off they would have to fix it to the way it arrived.
