The ride-sharing market isn’t exactly crowded, but it’s extremely competitive. Uber is the only ride-sharing service that operates on a global scale, and is the undisputed market leader, but it still has to work for its money. A number of local ride-sharing services have ensured that Uber doesn’t go unchallenged, especially in Asia, and it’s even having to face stiff competition in its home market thanks to Lyft. However, the number of American competitors decreased by one earlier today, as Sidecar co-founder and CEO Sunil Paul has announced that his company is pulling out of the ride-sharing and crowd-sourced delivery market in order to focus on other areas.
