From personal (European) experience, I can also recommend it. If moderately used, it's dirt cheap compared to owning a car. I spend about as much on it as just renting a garage would cost me in Brussels.

I was not a heavy car user even when I had a company car, but I do notice that I try to organize things even better so as to e.g. minimize shopping trips (do one trip for the big stuff every x weeks, use public transport or bike for the rest). And that's what the article completely misses: the system encourages behaviour that ultimately benefits the community, regardless of the individual user's noble or less noble intentions. (For the record, I certainly don't see car sharing as a temporary solution before getting my own car.)
