Erik, there is a blaring horn..........mine. Anyone caught texting or talking on their cell should have it confiscated until their court appearance.
I voted yes but with tongue-in-cheek. They installed the roundabouts on Rt 55 to alleviate traffic. Before installation, my traffic alert app (read before leaving home...no, not in the car) indicated a morning 6-8 min delay on Rt 55. After roundabout installation, my traffic alert app indicates a 6-8 min delay.
Perhaps a blaring horn should go off when lights turn from red to green, alerting texters to look back up at the road and move forward.
If they have lasers that vaporize cars, then I'm going to go with "yes", I think they can help.
