Pony AI Inc. (NASDAQ:PONY) founder and Chief Technology Officer Dr. Tiancheng Lou said the robotaxi industry cannot achieve true Level 4 commercialization through simulations alone, arguing that companies must collect massive amounts of real-world traffic data and build advanced world models to scale safely.
Real Roads Still Matter Most
In a Financial Times op-ed published on Sunday, Lou wrote that "launching a robotaxi is becoming easier but building one that can scale commercially and operate safely remains difficult." He said the industry overestimated what simulation, compute and static datasets could solve, because autonomous vehicles change how nearby drivers, cyclists and pedestrians behave.
Lou said the hardest problems involve everyday ambiguity, including hesitation, informal signals and partial commitments. A scooter cutting across a pickup point or a driver edging into a gap can test a robotaxi more than a clean, ideal-road scenario.
World Models Cannot Replace Exposure
The Pony AI executive argued that companies must move beyond supervised driver-assistance systems. He said a company only truly competes in the L4 market once it operates fully driverless vehicles across complex, scaled urban environments. In his view, commercialization depends as much on fleet operations as technology, because companies need enough real-world interactions to improve.
Lou said "world models" can help systems understand cause and effect from real-world data, such as how other road users react when a robotaxi slows or behaves cautiously at a junction. But he said those models cannot replace road exposure. “It is on the road, not in the lab, that the autonomous driving race will be won,” Lou states.
Robotaxi Race Keeps Getting Crowded
Pony AI, an artificial intelligence technology company focused on autonomous vehicles, says its PonyPilot service operates robotaxis in major Chinese cities. Its website describes PonyPilot as its robotaxi business, while the company has also developed L4 autonomous trucking technology.
Alphabet Inc.-backed (NASDAQ:GOOGL) (NASDAQ:GOOG) Waymo remains the U.S. market leader. Waymo said last year that Waymo One provided more than 250,000 paid trips weekly across Phoenix, San Francisco, Los Angeles and Austin, with plans to expand to Atlanta, Miami and Washington.
Tesla Inc.’s (NASDAQ:TSLA) is also pushing into robotaxis. Elon Musk has touted a future large autonomous fleet, though investor Ross Gerber has criticized Tesla's Full Self-Driving system as "problematic" and said Waymo performs far better.
According to Benzinga Edge Stock Rankings, Pony AI stock currently offers a poor Momentum score and an unfavorable Price Trend recommendation over Short, Medium and Long term.
