That's wild. I wonder if you just have a couple of jerks in your area. I grew up in a rural area and my parents still live out there, and I cannot ever remember someone driving on the road with their light bars on. I used to have one on my jeep. Anyone who has them knows they're being a jerk if they're driving with it on the road.
In the Rockies you see loads of vehicles with light bars. Never see them lit up on the road. Maybe it comes down to local policing? Cops around here aren’t likely to appreciate non-locals driving with lights on. Could just be culture though.
I would like to think so but i saw the same crap driving through the middle of a Denver on I70 recently. I almost had to pull over it was so bright I couldn’t see but no one did anything as I have become accustomed to.
It's super common in the south nowadays. I grew up similarly, and had light bars on my trucks/all my friends did/etc. But we weren't driving around town with them on.
