I used the Navigator to route me from Austin to my home in Houston. My Energy Page and my Rated Range said I had 120 miles of charge but the Navigator said I would not make the 90 miles to the Columbus supercharger and routed me to the San Marcos charger first. I decided to be conservative and follow that advice. After charging in San Marcos I moseyed onto Columbus and charged up to 140 miles, well beyond what the Navigator said I needed to make the last 75 miles home. After about 5 minutes on I-10, I got the yellow warning that I should slow down or I would not make my destination. I dropped from the 75 mph speed limit to 65 mph. Then about 10 minutes later the Navigator turned red and said I would run out before I reached home and would be 20% short of energy. However the energy map and the rated range both agreed that I had 120 miles of charge left to make my 75 miles. I continued on hoping that the Navigator would change its mind after a few miles but it never did. About 35 miles from home with the warning still in place I cancelled the route and re-entered a route for home. Now the Navigator came up and agreed with the energy map and the rated range that I had more than enough miles. I arrived home with about 65 miles of charge still remaining.
It occurred to me that the Navigator may have been computing energy requirements for a round trip but if so that is not necessarily a good automatic assumption. Any thoughts?
