To rid the disease, you have to excise the source:
Graphic from ThisBigCity.
Of course, increased car ownership is not the source. It is the symptom. A by-product of a lack of real choice, which is the real disease, rampant and reckless public spending that builds barriers rather than empowering.
Not coincidentally, I received an email from a total stranger late the other night. This person was staying at the Hyatt. You know, the hotel with the little golf ball on a tee out front. She was desperate to be able to walk somewhere. Where she wanted to go was less than a mile away from her. She reported that the hotel staff laughed at her inquiry, which led her to me. I could do little more than advise against it and have concierge call a cab. These are the things that happen when your city isn't built to facilitate social and economic exchange, the fundamental purpose and long-term raison d'etre of any city. Lacking this, the life spans of city's veering from this path will be as short as the short-term goals of their chosen 'prime directive' in the operating system of their city's software.
In other words, moving cars at the expense of all other considerations is a poison pill.
