What I do know is that small businesses managed to adapted, sometime for the good, sometime for bad.
An example would be the plumbing industry, the local plumber only come round when the congestion charge is not in effect, which is a bit annoying when the boiler isn't working and you have to wait till the evening for him to come and fix it.
The*** plus size*** is that some plumber decided to ditch their vans and took public transport, I remember seeing a plumber in the tube with his tools heading to work, only if the cilent's problem is a small one enabling him to carry a small amount of tools that is.
There's a plumber who went out and brought himself a Kona Ute, and use that instead of his vans, which is a positive change that should be encourage.
In the end, businesses can adapt, it didn't halt the economy in London, but merely adapted it, and those who didn't adapt to the change end up being shafted.
