“Also they think it will help to put on their hazards. It really just draws more attention to the fact that they’re parked by a hydrant. “
Meno: It does help because hazards at least unofficially signal, “Wait I am not parked, I just had an emergency stop.”
When I drop someone off at the airport, there is no parking allowed in the Departures strip. I pull to the side, put on my hazards, and then give a hug goodbye and maybe get something out of the trunk.
The question here is are you talking about people who park, walk away from their vehicles, and leave for hours at a time. Leaving their hazards on?
Hopefully their batteries still have charge upon return.
