Several times, the National Highway Traffic Safety Administration has delayed rules for rear visibility that would require backup cameras since Congress required them in 2007, but they can't come fast enough for me. It is much safer to watch a screen on your dashboard that has helpful yellow guide lines than to twist your neck over the back of your seat, look around for blind spots, and then try to back up. And don't omit those helpful beep beep beeps that let you know when you've gotten too close.
Some of these new cars are already scheduled for earlier-than-usual facelifts. The rest of them are already overdue.
