BTW, if you have a mobile phone, you can be tracked by GPS to within
a few metres - even with it turned off.

Incorrect.
We can track a mobile, but not that accurately ... and it has to be
switched on.

That's not the information that I have read, but I stand to be corrected.
As far as I have found out, even when switched off, a mobile phone emits a
carrier wave that can be detected.
