You can’t talk about safety features in new cars without highlighting the role cameras now play. As mentioned in my last column, tiny lenses built into the bases of rear-view mirrors and trunk doors help drivers see everything from what’s behind them when backing up to speed-limit signs.
But two points made by car-camera guru Andy Whydell surprised me. The first is that, while car cameras can do sophisticated things, they are for the most part extremely simple devices, with a top resolution of about one megapixel. (A cellphone camera could easily have five times that resolution.) Rarely do they shoot high-definition video, he added.
