It may surprise some to learn that ridesharing as a percentage of commute mode share in the US is relatively high compared to other developed countries. The table below shows the mode split for commute trips for the US, Canada, the UK and Australia. The US has a substantially higher level of ridesharing than any of the other three nations. It is interesting to note however, that all three other nations have substantially higher public transit mode shares than the US does. If the two modes (carpool & public transit) are considered together, the combined share is quite similar across all countries. This may suggest that the two modes compete with one and other, as suggested at several points on the website. Further, this assertion is supported by the fact that the strongest rideshare markets in the US have relatively low transit shares, and vice versa.
