To the editors:

By now millions of true geniuses must have let Cecil Adams know the real reason one turns off the car lights [March 2].

Because if they turned off automatically they would turn on automatically. And everyone would drive all day with their lights on. Or–there would be a turn-off switch for days and we would be back to square one. Or–we could pay $50 or $100 for a sensor system that would turn them off in daylight.

Too simple to come to mind?

Cecil Adams replies:

Thanks for that valuable input, Perry. Now everybody can see what I went through when I talked to those mopes at GM.
