Remember how all the Saab owners used to wave at each other in traffic? i can see that kind of comeraderie coming back with the Smart owners. I will propagate it myself when I have mine and meet or pass another Smart. And overall, I too, think it will make people happier and I'm for that. Too much damned negativity in the world today I think.
Same thing with the MINIs. First 3-4 years, lots of waving. Now, nothing.I remember some of that when Saturns first came out. They were unique to look at, and (at least according to reports), the employees were happy to work at Spring Hill.
Now that they've been around a while, you don't see it anymore. Things fade.
Now, of course, it's just another GM product; their new car (the Astra) is just an Opal Astra with a Saturn nameplate.
