This is a good point - if you've gone to the trouble of insuring a car and paying for a parking permit, AND registering for the residents' C-charge discount, you'd be a fool not to drive whenever it's convenient.
Zoe you're right that the cars-per-person ratio must be the lowest in the country but there are still a lot of cars owned in the area. And in the parts of SE11 where you get 90% discount. "
I think that if the discount was reduced to say 50% it would change the economics of the situation. At the moment, the decision whether you drive you car is really made by owning the car and having it registered with all the discounts. However, if you live outside the congestion zone, you would have to think several times before driving into central London.
Agreed. I haven't bothered re-registering for the discount since it last expired, and as a result I don't drive in the zone during weekdays unless it's really really worth £11.50. Previously, when it only cost me a quid, I drove a lot more often.
However it's one of these things that ensnares people that really value every tenner*. The folk least affected are the ones with most money...
