I think the GOM is a slow learner as I have been the only driver for 3+ years and set in my driving ways (age 85+).
Of concern, is the battery state.
I assume I am measuring the "actual range" when I calculate the (actual miles driven / batt.-energy-used) X 100.
The last 3 trips (Mostly freeway at 62 mph) avg. 118 mi. for this "actual range".
My GOM shows avg. of 85 mi. at the start these trips (with 100% batt.).
