For those of you interested in a working model that has been operation since the 1980s go to www.mobility.ch
If you want see the page in English (click on the "E" at the top of the page)

When looking at the impressive growth figures on the website, remember that Switzerland only has a population of 7.5 million and has a working public transportation system that is complimentary to this business model. The prices are in CHF (Swiss Francs) which is almost at parity with the USD.

Note that Mobility has also partnered with many nationwide businesses as well as offering a service to professionals (much like Penske has done in the US for truckers). All these parallel business streams have sustained the business over the years.

Oh, did I mention that gas prices are over USD 7 per gallon in Switzerland?
