A day in the life of

So, I went to Landshut today and then back to Munich, Neuperlach and I didn´t see any Speed Controls (blitzer).

My Theorie for the day is-

Is it possible than the when the weather ist hot like yesterday( it was 28 degrees in the car, sometimes up to 30) that the police can´t do the car blitzing, because it is too hot for the policeman sitting in the car?

There hast to be someone present in the car when the blitzer is activated. Has anyone else noticed this Phenomena. Maybe there is a Temperature, where we observe no blitzers. The fixed ones don´t have people operating them. Maybe the Police man standing with a laser pistol has some temperatür limitations too. I recently saw two hiding behind a tree at as " Ortsausfahrt" close to Weilheim with a laser pistol. They seemed to be using the tree as a shade.

Any comments would be gratefully accepted.

The second theory is-

Schould lorry drivers be allowed to listen to loud music and telefon while driving a huge mass. We would all be somewhat disturbed if the pilot of a plane started listing to ACDC I am sure. After the recent increase in "Lastwagen Accidents" around Munich, I started thinking about the reasons. The tiredness thing is also a factor and maybe the Air Con is inadequate to keep them awake. Sometimes they "streif" other cars without even noticing it, because their lorry is so big and makes so many other noises on top of that they may be listening to ACDC or soemthing similar. I know car drivers do too, but the consequences of a 30 Ton Lorry are a lot bigger than that of a car.
