You are describing one of my favorite games from my youth, "Dead on the Road."
Back in the days of yore when our computer was an Apple II+, only the very very rich had cell phones, and I had already beat River Raid, Moon Patrol, and Vanguard on my Atari, I would occupy my free time with my friends taking turns sprawled out on the side of the road. Maybe one in twenty cars would actually stop and show concern only to be rewarded by a pimply kid flipping them the bird (or mooning them depending on our mood) and running off into the desert. We spent many afternoons this way until we had the holy crap beaten out of us by a primer'd dodge full of stoners.
As you can probably guess, my parents spent a disproportionate amount of their free time fielding "guess what your son did this time" calls.
