Normally I don’t give a crap about blind spot monitoring. But last night, I was in the middle lane going like 70. The person in front of me was going like 60. There was NO ONE else on the road. So I checked all around behind me, saw nothing, and went into the left lane. Just as I was about to, the blind spot detection kicked off. Some motherfucker was going down the left lane in a black car with no headlights on. I got in behind him and flashed my high beams at him. He moved over and kept driving with no headlights. Idiot!!
At night, the glow of your headlights extends hundreds of feet. So even if you’re in their blind spot, they’ll see a huge beam of light next to them extending from their side view and tens of not hundreds of feet in front of them.
