Yes, John Humphrys on R4 this morning said someone had emailed him to say something similar - he asked whether his email spam filter knew something he didn't, regarding anything communicated by Blair :-)

I haven't seen my Blair email yet, so I assume it was also binned on arrival.

What I want to know is: how will they pilot it? Who in their right mind will volunteer? Or will they just say "everyone in Birmingham will have GPS fitted to their cars at their expense and be charged per mile, while the rest of the country continues to enjoy motoring relatively free of government interference and extra charge"?

Unless they intend to pay people to take part in the trial, and pay them more than they expect to collect in fees?

Does anyone know how this will be done in practice?
