How fast do you normally drive?
I've heard both sides. For my, it's the opposite (and I speed), trip planner estimates my travels pretty well.
75-80. I would think it would learn from the consumption during the previous leg, but it just turns around and estimates an optimistic number that subsequently loses 10% after I'm on the road again.
I have the S60 refresh with the 8.0 update.
I was surprised I couldn't find anything about it in my online search.
See post #341 where the suggestion is made to arrive with >10 miles:
Some California Superchargers not providing maximum charging rates
There have been others but I can't find them now.
