I think it's ridiculous to extend it into Tower Hamlets, the poorest
borough in London. There would be bound to be people who were outside
the congestion charging zone but whose local supermarket or school or
similar important service was inside it, and who'd be left with no
adequate substitute method of transport. And for people who really
don't have a lot of money, that would be very unfair.

They might even be forced to sell their cars.
