Good. However, if the intent is to discourage driving in central London, the penalty should not be an fixed rate for each vehicle. It should be a dynamic rate based on how much the people in the car earn. Otherwise you are only displacing people with low salary while freeing the roads for the rich that don’t care to pay £30.

I have genuinely noticed how much cleaner the air has been since they introduced these charges, so I for one welcome this.
