I discovered a thing!
Anyone else with a Toyota hybrid have that annoying thing, where you reach for the EV Mode button and it says "bleep bleep mfker - EV Mode Unavailable"? Despite your hybrid battery being plenty charged, and even after a long drive?
I back into my attached garage everyday, so it sucks to have it spew fumes in there.
Anyway I realized you can shut the ICE off by sticking it in the P. And when you next go into R, the car's usually too lazy to turn the ICE back on unless you're hard on it.
I mean sometimes it'll come back. But a couple more thrusts into P usually beats it back into submission
