No wheels being reinvented -- just relatively dim old brake lights being made brighter. I can think of a bunch of reasons why it's a good idea: our cars are among the few left on the road that don't have the central 3rd brake light (though obviously retrofits are possible). Today's traffic is a lot more dense than when our cars were new. Today's drivers are a lot more distracted, too -- talking on the phone, texting, putting on DVDs for the kids, futzing with the stereo, etc. Crash repair parts for our cars are a lot harder to get than they were back in the day.
