Summary
- Uber and Lyft did not achieve their promises of being a first/last-mile connector to public transportation
- Uber and Lyft actually increased traffic and displaced biking and transit trips
- Robotaxis in San Francisco have not shown a net positive impact on the transportation system
- Driving around with empty robotaxis waiting for passengers adds more miles on the road
- There is a fundamental tension between convenience for the wealthy and the needs of the transportation system

The discussion surrounding robotaxis often focuses on their efficiency and scalability, but the potential benefits of this transportation mode have not been thoroughly examined. In an interview with former director of the San Francisco Municipal Transportation Agency, Jeffrey Tumlin highlighted some important points about robotaxis. He mentioned that Uber and Lyft failed to achieve their intended goals, creating more traffic and displacing biking and transit trips instead of becoming critical connectors to public transportation. The increase in vehicle miles traveled in San Francisco due to Uber and Lyft has had negative impacts on the city’s transportation system.
Regarding the robotaxis roaming San Francisco’s streets, Tumlin noted that there is no discernible positive impact on the overall transportation system so far. While they may offer convenience to those who can afford them, they contribute to congestion and inefficiency in the transportation network. The use of robotaxis results in more miles on the road compared to traditional means of transport, as the vehicles often operate empty while waiting for passengers and traveling to pick them up. This inefficiency poses a threat to the economic vitality of San Francisco by hindering the movement of people through the city.
Tumlin emphasized that flooding the city with robotaxis would worsen congestion and reduce the overall efficiency of the transportation system, particularly if these vehicles are replacing walk, bike, or transit trips. The tension between catering to the needs of the wealthy, who are more likely to use robotaxis, and the broader transportation system’s requirements is evident. While autonomous vehicle companies may aim to make their services accessible to a wider range of income groups, this expansion could lead to a significant increase in traffic, which negatively impacts everyone.
The potential for robotaxis to serve a broader audience beyond the wealthy hinges on these companies reducing costs and improving accessibility. However, this expansion would likely result in a significant increase in traffic and congestion, posing challenges for urban mobility. Tumlin highlighted the fundamental tension between providing convenience to the affluent and addressing the wider transportation system’s needs. Finding a balance between these competing interests will be crucial for the successful integration of robotaxis into urban environments and sustainable transportation networks.
