I once had this happen to me. When I reached their window, they threw a half-full beer at me. I was 14. I came home smelling like beer. My parents knew I wasn't cool enough to be drinking beer at 14, so I didn't get in trouble at all.
Driver: that thing looks pretty fast, you wanna race?
Cyclist: sure, switches bike to max assist
Driver: Toot, toot, toooooot!! (loud roaring of engine)
Later at the pub
Driver: I can't believe you had me for the first 100m, fuck that thing is fast
Cyclist: I know but the top end isn't really what I need. Another round?
Driver: Sure one more, then I have to get home.
I literally once had someone yell at me for riding on the road, then someone else yell at me for riding on the sidewalk - in the same day. More like within a few hours.
