As cities continue to grow and urbanization shows no sign of slowing down, local governments continue to struggle with their public transportation systems due to ongoing budget woes and federal government cuts. Some studies have claimed that ridesharing can contribute to thriving public transport plans; others say that the wonky and still unprofitable business models of Uber and Lyft actually could disrupt our future “smart cities” and turn them into a mess. And as speakers repeated during a recent Ford event in San Francisco, the convergence of self-driving cars with an electric drive train will do little good if streets are still congested with cars shuttling only one occupant at a time.
