[03/05] Since you can fix the car's brakes yourself (though it will have to pass inspection), there is no reason the car's software should be treated likewise.

What about car hardware that can do surveillance? Laws should require that any cameras that can see outside the car, or passengers, be designed to blur out their faces, bodies and clothing, sufficiently that the car's computers learn only that there is something there and its rough dimensions (accurate no more than to the nearest foot).
