Very recently I was driving on the Autobahn. It was a relatively crowded Sunday. Then cars in front of me slowed down a little, I saw two cars on the side of the road, then a lonely car wheel rolled right in front of me, nearly missed my bumper, I only had to break slightly. I was startled but fine. Saw one or two more cars on the side, they all seemed fine. I wondered where the, now three-wheeled, car was. About a kilometer further there it was on the side, already sitting on a car jack, so some time must have passed already and no one seemed injured. This wheel must have rolled around on the road for a while, hitting a few cars on it’s way. I was reminded of the movie “Rubber”.
I don’t know what you mean. I asked why do we need clocks on ovens. You said “to time cooking” but you can have a timer without a clock so it is still not needed and your answer is invalid.
