Very few people in that part of London *require* a car. It is a
lifestyle choice, not a necessity for the most part.

Aside from people that work outside the train/tube hours (i.e. start
before 9AM on a sunday). I'm thinking about nurses at Chelsea &
Westminster Hospital for example. Basically unless you work government
hours you're forced to risk a dangerous night bus that takes 3 times
longer than a car, and that assumes there's a direct bus from where you
live to where you work, highly unlikely.

I'm writing this at 02:31 on a Monday morning, from work, just outside
the new extension area. Won't affect me directly as I live west of
London. Many of my collegues will have to take a new route in though,
along more congested roads.

While I'm just outside the zone, If the building was 800 yards East
we'd be in it. It's going to cause enough problems with added traffic
arround the bush at lunchtime (when some of my shifts start - yes, the
shopping centre wont help either). FYI the last tube east from work on
a Sunday is 2327, the last train west 0005. Not much good when you
finish at 0030.

But journeys in the zone will speed up by 5 minutes. Assuming 2
journeys per day, for an £8 cost, the point of the zone is to make
life easier for people on more than £48 an hour. Ken - the rich man's
mayor.
