On the Mobile Phone While Working?

It seems that recently I come across many people that speak on the phone while they do their work. In Toronto on the bus to the airport the driver spoke on the phone (telling someone how to find and edit a file in Windows) while driving. Here in Bonn I saw it in shops and on the ferry – it felt really awkward to interrupt people in their phone conversation just to pay my ticket or bread.

At the moment most people speak while holding a handset – but given they use BT-headsets one could image new working practice ;-) e.g. driving a bus and doing a call center job on the side. I would expect there will be some regulation soon…
