We're discussing events inside. I think you'll find that the car was outside the vehicle - perhaps you should watch the clip again. > Care to try again? Q: Can you hear a trucks engine noise from inside the cab? A: yes Q: Is the car tyre noise louder than the engine noise when compared from an equal distance? A: yes - check the clip. Q: Given than the car noise is louder than the engine noise and that they both originate from sources pretty much the same distance from the driver's ears, which would be louder? A: The tyre noise This can all be gathered by watching the clip (with your brain turned on).

You can't see what is directly in front of you in a truck - you > already told us that. But a good driver will have noted where the object was before it disappeared from view. A good driver will also know approximately how far in front it was when it disappeared from view due to familiarity with the sight lines form their driving position. Visual clues form other objects (e.g. through the side window) allow a good driver to pull up quite close. MBQ

How does it corrspond to the frequencies being emitted from (a) the scraping of the car (b) the engine noise? " The frequency response of mobile phone mics are typically between 300 hertz and 3,400 hertz, which is somewhere between the high pitched squeel of tyres on tarmac and the low gritty noise of a large diesel engine. Despite the noises being outwith the phone's sensitive response range, the phone would picked up both noises with equal sensitivity.

If you are now telling us that the > driver could see the car through his side window, then you have rather > destroyed your already flawed argument! No driver can see whats *immediately* in front unless it is tall enough to appear in their line of sight. it doesn't stop most drivers being able to pull up very close to low objects that they lose sight of as they approach.
