Robotaxi leaders say real traffic tests are key to safer service

In short: Robotaxi developers say testing in real traffic is essential because other road users change how they behave around driverless cars.

What's going on

A Financial Times opinion column says the robotaxi industry is entering a noisier phase, with more companies showing off driverless taxi plans. The writer, Tiancheng Lou of autonomous vehicle company Pony.ai, points to events like the Beijing auto show, where robotaxis were more central than in past years.

The column argues that progress will not come only from lab work like more computer power, more training data, or more simulation. Simulation means practicing driving in a computer-made world, like a flight simulator but for cars. That can help, but it cannot fully capture how humans react when a robotaxi behaves in a cautious or unusual way.

The key problem is a feedback loop. If a robotaxi slows down, hesitates, or pulls over differently than a human driver would, nearby drivers, cyclists, and scooter riders may respond in unexpected ways. The writer says these everyday moments, like negotiating a merge or a pickup spot, can be the hardest cases.

Regulation also affects how quickly companies can learn. Some cities in China and the US allow limited paid driverless service in set areas, which creates more real-world driving data. The UK and parts of Europe have moved more slowly, which can leave companies with fewer chances to test.

What to watch

The column says the next few years will matter because safety and cost both decide whether robotaxis can expand beyond small zones. It also highlights “Level 4” autonomy, which means the car can keep driving safely even if something breaks, and can pull over safely if needed. Watch for which cities allow broader real-road testing, and which companies can run larger fleets without making rides too expensive.
