While the continued growth shows Lyft is holding its own, it still has a long way to go before it catches up with Uber. Founded three years before Lyft, Uber reached the one million rides per day mark in 2014 and as of a year ago was giving an average of 5.5 million rides a day. Uber just recently surpassed its five billionth ride. But Uber has taken a hit recently. Business Insider reported last month that Uber's market share fell from 84 percent earlier this year to 77 percent by the end of May and Lyft saw a substantial jump in activations in the week after the #DeleteUber campaign.

Lyft has continued to adjust its service in order to make its ride-sharing more convenient for customers. And like its rival, Lyft is also working on self-driving cars. The company said in a post, "Since day one, we've worked to embed hospitality in everything we do. As more and more people choose Lyft and we continue to grow, we'll remain focused on providing the best experience to our passengers and drivers."
