In my experience, people do sometimes do what your husband says. Not everyone, obviously, but a lot of people really are shitty. So I get that to a degree.

A thing I do actually is that when I'm the first car sitting at a red light and my intention is to turn right, I actually explicitly do NOT use my turn signal. I use it in every other scenario except this one. Because I've found that if I use it, I run into the occasional asshole that decides to blare his horn at me for not immediately turning right and getting into an accident with oncoming traffic. When they don't know whether or not I'm turning or going straight, they don't honk at me like an asshole.

It's not that I never make right turns on red, it's that I just like to make sure it's safe to do so. I watch oncoming traffic and check the crosswalk for pedestrians. If there is an obstruction to view of traffic (happens occasionally at certain intersections), then yeah I just wait for the green light. But inpatient dipshits don't give a shit because it took them an extra 3 seconds to get to the grocery store.
