I do if a text came in or if I need to send one out, but only very shortly, and while checking the light every two seconds or so. Can remember the last time I had to be honked at. I agree thoroughly with your sentiment...my honking has grown tremendously in the last year or two.
These are the individuals. They should lose their license and their phone privileges.Frequently, the light turns and the car in front sits for several seconds until I honk. They are messing with their phone. Driving down the road, when a car slows down and speeds up, or are veering towards the edges of their lanes, it could be drinking, but more likely it's PHONE!!! And I'm convinced that that unusually high number of accidents that occur in my planned community where the speed limit is 40-45 mph on the main thoroughfares are due to people driving in traffic, following too close and messing with their phone, so they don't see it when the brake lights come on, it seems like every frick'n day.
I must say that all responders here are very sensible. I guess those I have honked at recently don't subscribe to this forumNo. $163 fine here if you're caught doing it at a traffic light or stop sign; $427 if you are caught while the car is in motion.
If the phone or whatever message is so important that you can't concentrate on driving, pull off the road. I'd rather people do that than not pay attention and hit someone.
