Maybe it's because I live in SoCal, but I see other Insights several times a week. There are two silver Insights that traverse the 91 Freeway West in the morning (both have car-pool-lane stickers, I don't!), one driven by a man, and the other a woman, at approx. the same commute time.
On my commute home, I've seen the silver driven by the male a couple of times, but never the woman (on the way East). Neither wave, no acknowledgement of any kind. Guess they're just not as excited about their Insights as I am about mine!
I see a blue one now and again, usually on the 405, and the only Citrus Insight I've seen was parked in San Clemente, no one around. Oh, and I saw a blue one on the climb (backside) to Torrie Pines (I was on my bike though), and a blue on on the Embarcadero in Morrow Bay last weekend (on my bicycle again, however, so they had no way of knowing I was an Insight owner).
For every Insight I see, there are about a zillion Prius (or so it seems). And who can tell a Civic Hybird unless you're right behind them on the freeway? Too stealth to make a statement!
