There is a following somebody in a snowstorm for miles with their irritating fourways flashing no matter what the speed. Flashing lights on a slow moving farm equipment for half a minute in clear weather is another.
You keep sticking to this
one scenario (and yes, I've read your following 3-4 posts). We get it;
constantly 'on' hazard lights irritate
you to apoplectic heights.
However, you are consistently changing the goal-posts of provided examples to suit your own 'position'. "half a minute" to go 500 metres (let alone 5-7kms) is ridiculous.
Here's another scenario... actually, it's a true story that happened to me many years ago. I was driving in upper-state Maine, on my way to Nova Scotia. It was night and there was heavy to medium fog. My headlights were on low beam, no hazards and there was a vehicle about half a mile ahead of me.
Suddenly, the vehicle ahead puts their hazards 'on'. They're still moving, so I become even more alert as to 'why'. The short story is that there was a moose on the 2-lane highway... scared the crap out of me 'cause all I saw of it was four spindly legs & its underbelly.
Had that conscientious and courteous driver ahead of me
not put their hazard lights on to warn me, half a mile behind him, I shudder to think what the consequences for me could've been.
