London has become the latest city to offer robotaxi rides to the public, with UK tech company Wayve's autonomous vehicles now available through the Uber app. The service launches with just 15 modified Ford Mustang cars, each staffed by a licensed human safety driver ready to intervene if needed — a regulatory requirement that stops short of the fully driverless operations already running in parts of the US, China, and the UAE. Uber describes the milestone as a key step toward eventually making rides both safer and cheaper, though industry leaders acknowledge that autonomous vehicles are not yet cost-competitive with human drivers.
