I've also started glancing left & right going through the green even if it's been green a while.
Once the traffic in front of me stopped suddenly, I stopped, and the truck behind me didn't and totaled my car, nearly killing me. Since then I glance in the rearview mirror when I have to stop hard, which paid off one day when I figured the guy behind me wasn't going to stop in time, I pulled off onto the shoulder, and he hit the car in front of me.
This is what I was taught when I learned to drive 20 years ago, and texting wasn't really a thing back then.
Perhaps, but I too frequently encounter the notion that having the legal right of way means one doesn't have to look. I've especially encountered this with bicyclists. Sometimes they'll tell me that it's ok because if someone hits them, they'll get a huge lawsuit judgement. I counter with what good is that if you're dead or crippled?
Some people I just don't understand.
This has been the case for years. When people aren't paying attention they are pavlovian in staring forward when they notice movement around them. But this doesn't necessarily have to coincide with cell phone usage, just bad driving.

I've seen an increase of motorcycle cops lane filtering at traffic lights, looking into the laps of the drivers. If there's a phone there, they're booked.
