My Austin gasser always gets attention, and most the time I like it. But occasionally it's the people's way of getting my attention that is irritating. I've had people suddenly honk their horn so I'll acknowledge their thumbs up, and it scares the heck outta me if I'm driving.
I've also had the idiots who are standing on the sidewalk and jump out in front of me to give a thumbs up, and that also is not cool.
Most people just smile, or nod, or take cell phone pics. Occasionally follow me to where I'm going and ask questions once I'm stopped. All those are welcome.
