Hollywood, go back to School

1. Car tyres don't squeek when skidding on gravel or sand.
2. Tape recorders don't play sound during rewinding or fast forward.
3. Hot water in a shower or bath does not steam, except in very cold air temperatures.
4. Sound does not propagate in outer space.
5. Electric power shorts do not spark like Fourth of July firework.
6. Few computer user enter commands with the keyboard as in DOS-times. Many years ago Apple introduced the mouse.
7. Altimeters in aircraft NEVER unwind like clock hands gone wild at 60 rpm.

Apparently, few people ever complained about these capital goofs.

• The sound track for fast cars in a curve on loose ground invariably originate from takes on asphalt/concrete.
  Is this meant to emphasise speed accoustically at the cost of authenticity?
  
• Are viewers too stupid to realise that a tape is rewound, unless there's an accompanying upspeed squeal?
  
• Are we incapable of believing a shower is warm in the absence of steam? Visible steam is recondensed vapour. The phase transition occurs after heating to 100 degrees Celsius (the temperature of boiling water to you fahrenheits) or if saturation exceeds 100 percent as the surrounding air cools down.
  
• Spaceships pass by and explosions in space occur in absolute silence. Why is "2001 - A Space Odyssey" the only film addressing an audience mature enough to expect basic physics even in science fiction.
  
• Fused mains supply, usually 110 (USA) or 230 Volt (Europe), invariably goes out with a quick, small, blueish spark. Computer electronics, about 5 Volt, do not spark at all. Not spectacular enough for Hollywood directors! So pyrotechnics have to provide the "spark" that triggers the "Aha - an Electrical Short!" in their grossly underestimated viewers' minds. One short will be pictured with as many as a half dozen firecrackers in as many different places. Accompanied, of course, by an endless series of just as unrealistic sound effects. In real life, if the mains goes, there can be no more sparks
  
• Have you ever noticed how incredibly old fashioned anyone operating a computer goes about his/her work in an average movie? Keyboards today, are used mainly for entering text.
  I admit that fingers busily racing over countless keys convey the idea of a wizzard or at least an insider at work. Of course, you would need two shots instead of one to show the result of a moving or clicking mouse on the screen. But is it worth showing hopelessly outdated techniques to an audience that knows more about computers that many a director?
