Summary

The companies began carrying passengers in fewer than 20 vehicles, with Transport for London allowing up to 15 cars in a one-year trial. The vehicles are licensed as private-hire vehicles, so removing the safety driver would require a separate automated-passenger-services permit that neither company yet holds.

Why it matters

London’s milestone shows autonomy can enter a major European market through supervised deployment before regulators approve driverless operation. A paid safety driver means this trial demonstrates operational acceptance and real-world testing, not yet the cost structure of a driverless taxi.
