Leaving on my first road trip in a few hours with my one week old 85D. The destination is Salem Oregon. There are two SuperCharge stations en route. The car is 100% charged and indicates range of 271 miles. The navigation says that I need to stop at the first one in Centralia, WA - just 40 miles from leaving home - for 30 minutes. The next is 110 miles down the down the road in Woodburn, where I am told to stop for 15 minutes. I don't understand why i would need to stop for 45 minutes at two station when the end destination is only 170 miles. Any thoughts?
