That exhaust has both CO and CO2 in it, proving that there is some type of fuel being combusted in the cylinders, despite what the computer readout is. If it were just air we would be able to breathe it.
When we activate the clutch after coasting in gear does the car shut off? No, it does not. Are we 'bump starting' it? No we are not.

I take it you are too lazy to do some research.
From just 1 of many links:
"
The Keep it in Gear Camp: Keeping it in gear, the vehicle's computer senses the reduction in power demand and shuts off fuel to the fuel injectors. When costing in gear, the engine is essentially off. This added resistance acts like an engine break, slowing the vehicle down but it does so with almost no fuel consumption.
"
Most new cars have fuel-cut off, where above a certain speed the injector duty cycle will be 0.
So its not just "my computer", it is everyone's computer.
You know even the instantaneous mpg reading on the frs shows 127 (If i remember correctly) when you coast in gear right?
