>>Once you make it no longer viable, people have no options left. Which implies that the people who continue driving are indeed those who have no other option, and those who do have taken it instead of paying the $9. Would you disagree? And no, of course I don't imply it's a lifestyle choice - merely that some people(not all!) were driving in NYC even though they indeed had other options available, because there was no extra cost associated with it - now that there is, those people use those other options where possible. Again, it's really fun to speculate why who and where is doing what, but if you have more specific data then please share.
