I agree that the usage seems very low. However, running rough numbers the gauge doesn't sound horribly far off. My average commute is about 25-30 minutes. So lets say:

The engine is on for 2/3 and off for 1/3.
Power usage is 6.5A with the engine on, engine off is 2A.

Engine on power usage is 6.5A * .33 hours = 2.15Ah
Engine off power usage is 2A * .17 hours = .33Ah
Total power usage = 2.48 Ah

Sounds reasonably close to me.
