GM has kindly offered to SELL you a kit to convert your current vehicle to DRLs. And, if they get their way, faceless government bureaucrats with no accountability to you, the voter, could make DRLs mandatory. The original concept for DRLs was to compensate for a lighting deficiency. Since we have greater natural light, the auto manufacturers have increased the intensity of their DRLs. Safety features need not create hazards and, more to the point, should not be so very, very annoying to so many people.
Some people respond to DRLs by avoiding looking directly at other cars on the road.
Some are even using devices which are already on the market to reduce the glare from oncoming DRLs. These actions by people will result in them being less observant, therefore, worse drivers and more accident prone. Current data on the safety benefits of DRLs has been misinterpreted by proponents of DRLs. They have absolutely no positive effect on bright sunny days. The solution, logically, should be driver improvement.
