My question is, what happens if you don't stop and let it idle down / switch injection modes? What if I leave my house right now and get on the highway and drive two hours without stopping? Will it stay stuck in port injection mode?

Once you start driving and pressing the gas pedal, the ECU changes over to 100% direct. The port injectors only inject at higher loads for supplemental fueling.
