Ride-hailing company Lyft has passed an important mile-marker in its self-driving car program by successfully delivering more than 50,000 rides, making it the most well-trafficked U.S. program of its kind. According to the company, the milestone marks a ten-fold increase over its total in August 2018 when the program announced that it reached 5,000 rides. The program currently operates 30 modified BMW's within a 20 square-mile area in Las Vegas where it delivers riders to some of the city's most heavily trodden areas, like the Las Vegas strip. Lyft has become the the largest ride-hailing program that lets users take self-driven vehicles. Lyft says the precedent is significant not just for the sheer volume of rides, but for the reported quality.
