... I mean everyone points at a recumbent enough as it is!!
They can be broken down into two categories almost without exception:
Positive reactions are by far the huge majority:
children/teenagers: squeal with delight, "can I ride it?", "cool where can I get one", nice ride, look at that, that’s so awesome,
geriatric riders: "that looks great"/ is it difficult to learn / completely unfazed regular conversation ("normal"),
Women: genuine interest, curiosity,
Touring or commuting cyclists and the occasional young/middle-aged male cyclist.
90% of people stopped at a crosswalk with you: interested / conversation starter
Negative reactions (very few) are limited to lack of eye contact and lack of response to waves or other recognition and mostly young to middleag
My instinct is to avoid talking with people on the street that I have never met before but this over-abundance of positive reactions makes it much less challenging. The only reaction that I dislike are the punk kids who ask to try it out of some extreme extrovert-ish machismo (possibly related to a mix of inferiority complex, teen-hormones, and showing off to the gang/girls).
