Apparently this is a radio show that, among other things, answers questions people send in to a man calling himself "Dr. Science." I've never heard the show, but recently I found the following account on line:

>>>“Dear Dr. Science, Why is the speed of light only 186,000 miles per second? Can't science do better than this?”>"Yes, you're right. It's a disgrace light only goes a measly 186,000 miles per second, but physicists are working on this problem. There's already a prototype vehicle that goes 200,000 miles per second, but the headlights shine at only 186,000 miles per second. This is equivalent to driving down the freeway the wrong way with the headlights not only out but actually chasing you down the road. This is why so many scientists today no longer own a driver's licence."
