One afternoon, while watching a radar-controlled German ubersedan drive itself, the fading sun struck my eyes. Surrounded by microprocessors, solenoids, relays, pumps, controllers, fans, sensors, circuit boards and endlessly coursing electrons, I did what every driver must do: I reached up for a vinyl-covered board and pivoted it down to cover a small patch of windshield through which I now could no longer see. Excuse me? The $105k four-door was crowded with technology, all of it entertaining, much of it only occasionally useful. Yet no one had thought to correct, improve, replace, redesign or reconceptualize a device as primitive as the Budweiser Clydesdales’ blinders. What’s that all about?
