Is this why Police often ignore mobile phone use?

Bin Man:
Most modern cars now have the ability to connect to the phone by cable or Bluetooth

Very true, and even if you’re driving some old 55 reg wagon with nothing but a steam-powered radio, your snazzy modern satnav will probably let you connect your phone through it’s own system (my TomTom does), so there is really NO excuse for a HGV driver getting 6 points for a CU80 offence, with potential Tea and Biscuits with the TC too.
