10 million. Light: 300000 km/sec, car: 0.03 km/sec

  My car is a lot faster than 108 km/h (0.03 km/sec) :)

    In the context of the speed of light, it really isn't.

      greydius corrected me asserting that the factor between ligth speed and car speed is 10 millions, and not one million as I said. But in true there are production cars that pass 430 km/h, resulting in a factor of about 2.5 millions. A lot less than 10 millions. https://en.wikipedia.org/wiki/Production_car_speed_record https://en.wikipedia.org/wiki/Production_car_speed_record

        You should not compare the fastest car speed, but the average car speed, which for this argument would probably be closer to 200km/h. That puts it in a factor of 5 million, which is within one order of magnitude of the original guess.
