I love stealth mode and try to get into it whenever i can. It's so smooth and quiet that i wish the car drove like that all the time. I'll usually accelerate up to 15mph using the ICE, then release the gas pedal, then depress lightly to engage stealth. It's great seeing only the arrows coming from the battery and the hum of the electric engine.
I love running on electric only with the windows down....people ask "wait its on". Sounds like a golf cart!
The last leg of my drive home is through the subdivision and I can usually get into stealth pretty easily. I really do enjoy stealthing relatively slowly, listening to the babbling brook, the birds, etc. And when there are people out walking in the evening, I can say "good evening" without raising my voice.
