The only direct commentary I've ever had on my HCH was a woman parked behind me waiting for the gas pump in an SUV. However, she wasn't mean or anything she just said it was a pretty car and asked if I liked the "hybrid" (she couldn't pronounce the word correctly at all).
I've had one person in my building at work ask if I drive "the white Honda Hybrid parked in the lot." We had a short conversation about it, told him my mileage (unfortunately, I drive so many miles that I'm still filling up every few days, but putting less fuel on each tank than I used to in my old vehicle), he brought up some kind of new battery they're developing to get a range of 1000miles+/- in all-electric vehicles ( I haven't been keeping up with those developments, so not sure what he was referring to ).
Then again, I work with a bunch of engineers, and I've probably seen about four or five other hybrids (one other HCH at the cafeteria parking lot, someone on one of my project teams has an Insight, and someone else in my building has a TCH which I purposely park next to from time to time,

), so I suppose they may be predisposed to liking them.
