Mine shows less than 30 miles on the fuel gauge if I let it go long enough. I think it was at ~15 miles that it switched to "LOW". If you completely "run out" of fuel (the car keeps a reserve in the tank that you can't use), it will switch to "Engine Not Available" reduced power mode and you can drive several miles in order to reach a gas station, but once those several miles are up, the car will shut down until you charge it or put more fuel in it.
