A relatively dense article from a credible source. Quite a bit of information is provided regarding the impact of, what is still in effect a truism, no matter who is doing the driving, more vehicles on the road concomitantly contributing to increased traffic and congestion. It takes some liberties with being a bit solicitous toward the companies referenced. Also, it is slightly contradictory in that in one paragraph the firms are criticized for not providing enough information (or rather more useful information) but later lauding them for providing information. Overall the article has the tone of trying to not give offense to the corporations in the hope that they will be more forthcoming from a data perspective. This article is a good effort but more detailed analysis can be gleaned from other sources. A possibility worthwhile read for those interested in public policy regarding non-public transportation alternatives.
