Driverless cars are facing challenges in emergency scenes, according to warnings from the NHTSA. These vehicles may have difficulty interpreting certain elements, such as smoke or flashing lights. Ordinary city driving may not reveal these issues, as driverless vehicles can handle routine tasks like lane markings and traffic lights.

However, emergency scenes pose a unique problem. Further details on this issue are available from TestMiles, which has reported on the challenges faced by robotaxi emergency scenes. The NHTSA warning highlights the need for continued development and testing of driverless cars to ensure they can handle a range of situations.
