The experience was interesting. I was on my way to the gas station. I got about a half mile away and the ICE failed to come on as I accelerated up the 3% grade on 55 miles per hour road. In horror I watched the charge needle drop like a rock while I maintained 35 miles per hour in EV mode. However I made it to the gas station and pulled up in line. I immediately shut everything down as the charge meter was at the bottom of the blue. When the space opened up the car moved about 10 feet and then died with 5 feet left to go. I pushed it to the pump.

I am happy to report that the ICE started immediately after filling the tank with 20.004 gallons of gas.

The early warning system resulted in on overoptimistic expectation of what was left in the tank.
