London is a mediaeval city with a current population of about 8 million.
Most roads there were originally built for the horse and cart.
Since various British Governments have refused to fund public transport properly (most politicians think a chaffeur-driven car is public transport - and don’t get me started on the privatisation of the railways), there are a lot of cars entering London each day.
I remember a recent claim that the average speed of a car in London during the day was 4 miles per hour.
There are always massive tailbacks each morning and evening going in and out respectively.
Recently the office of Mayor of London was revived and an independent, Ken Livingstone, beat all the major political parties.
A large part of his manifesto was the ‘congestion charge’, where cars pay £5 (about $8) a day to use Central London roads.
There are cameras on all routes into the centre to read number plates, and there are fines (starting at £40) if you don’t pay.
There are exceptions (one is any vehicle with 9+ seats), but it’s late so I won’t be posting them here.
To sum up, yes, it now costs money to drive in Central London.
It was introduced by a popular vote.
No, they’re not going to tax the air.
Yes, we have a National Health Service too.
