Imagine trying to flag down a robot truck after sliding off a rural freeway on a freezing winter night.
OnStar(tm) will take care of you.
Do people actually still attempt to "flag down" other vehicles when they have suffered a mishap?!
After all, it might be a "set-up" on the part of the alleged distressed party. Or the person who stops might be an unsavory type.
I would have thought that Standard Operating Procedure was to sit tight in your disabled vehicle and use your cell phone to hail for assistance from, e.g., the AAA.
Alternatively, your vehicle might itself broadcast an automatic distress signal to summon the authorities.
One might just as well lament that modern jets fly so high and fast that one can no longer "flag them down" like in the days of the old "Barnstormers."
If I've overlooked something: Forgive my ignorance! I've never acquired a driver's licence or a motor vehicle, and rely exclusively on public transportation.
