One of the things that appeals to business travellers about Lyft is the ability to book cars in advance, a service the firm unveiled earlier this year. With Uber, on the other hand, clients can only book a ride as and when they want it, and must hope that there is a driver nearby (although there nearly always is). That explains why Uber announced last week that it will follow Lyft’s example and allow riders to book cars between 30 minutes and 30 days in advance.
