i think it's much worse than that: first, most drivers are probably not aware of the problem at all (i mean that their (often brand new) car is part of the problem).
just consider e.g. the number of people who are driving in fog or rain without their headlight turned on... because nowadays the front lights are always on due to some law... but the back of their car is completely dark. and no amount of flashing any lights makes them realize this.
or the number of people who are clueless about the fact that the headlight agle can be adjusted on most cars today, and what that means and/or how that works.
second, it's the institutions that are failing here, which is *way more concerning* than some clueles people driving around on the roads...
