Guy Narcs On Two Ladies, Dude Threesoming In His Carport

Of all the plot twists in the nine-sentence SeattleCrime.com story, this one tickled my contemplative fancy:

The half-naked man was having sex with one of the women, while the other female was "naked and messing with the victim's scooter."

Namely, I want to know whether this is the first time in transportation history that a scooter's mere presence turned a simple outdoor threesome into a decadent outdoor foursome. I don't believe records are kept for these matters, but they should be.
