> What it is analogous to is getting "stranded after driving around barricades to enter a flooded stretch of roadway"

Kind of? But in this case somehow the driver is driving a bus, or their car is pulling other cars in due to gravity, or something? A motorist who ends up on a flooded motorway endangers themselves and some first responders - which yes, is dumb, but after that initial ripple it doesn't continue to propagate the problem to other people. You can't spread car stranding.
