I mean they're not wrong, but who the fuck thinks putting this on their car is a good idea? It's the same fallacy as tailgaters fall prey to. You want someone to speed up so you ride their ass, but they're just as likely (probably moreso) to slow down or maintain speed just to spite you. Same thing here. People are gonna follow close purely because they don't wanna be told what to do.
I give them credit for saying their piece. Tailgating leads to thousands of accidents and quite a few deaths every year. I do 100% want this to flash on my windshield when trucks do this shit. They're not getting anywhere faster and they're just endangering others.
Also the car seems working-class-ish. So more power to this dude.
I gotta repeat this story that happened last month when I rented a car to go to this work thing. I was in the passing lane of the highway passing cars in the slow lane. Behind me comes this Range Rover, flashing his high beams like he's an ambulance. I was just like, "no", and ignored him.
I spotted a cooler and a bunch of lads in the car, so I'm not buying that it was a legit emergency.
