Dear Sir/ Madam,

Re pollution charges, Tuesday's Oxford Mail, are the councils conning the motorists, or are the councils being conned by the fancy measuring equipment?

Read again: Drivers could be charged £10 a day to use Oxford city centre from later this year

The sums don't add up, and it would be a logistic nightmare to implement.

Yours sincerely,

W Carter
