Uber continues to dominate car-related ride hailing transactions in the first quarter, according to the latest SpendSmart report from Certify, an online spend management solution, which said its results were based on more than 10 million receipts. The rideshare giant was responsible for nearly 73 percent of all transactions in its category, while Lyft took close to 22 percent – up nearly 4 percent over the same quarter a year ago -- with taxis accounting for the remainder. Uber was also the least expensive option among business travelers, with an average receipt of $25.19 compared with $25.32 for Lyft, while taxis had an average fare of $33.53. While the average Uber and taxi expenses have remained about the same from year to year, the average Lyft price increased nearly $6 over that time. The report also showed extensive use by business travelers of scooters, with Bird the front runner with 46 percent of all receipts/expenses, compared with 42 percent for Lime and 8 percent for Razor.
