The traffic circle flanking the Arc de Triomphe pulls in a dozen avenues and lets newcomers entering the flow go first, while lane lines vanish and every kind of vehicle hunts for openings. That mix of squeeze plays, start and stop moves, and surprise cyclists is exactly where automation gets stretched, because local rules and lived reality do not always match what a map or model anticipates.
Against that backdrop, a Jaecoo 7 SUV using Momenta Global's automated driving tech slipped through the mess, looped the circle, and chose an exit without asking for help.
These were separate drives around the Paris Motor Show, not a lab test, and the routes varied. Still, the differences were clear.
Chery Automobile's Jaecoo 7 ran Momenta's R7 driving model and took on the Arc de Triomphe during the busiest part of the route. It finished the longer, more complex outing without a single intervention. Not perfect, though.
Without countdown timers, it sometimes jabbed the brakes at lights, and when a car blocked its lane, it skirted around late in a way that felt clumsy. Chery's setup with Momenta also allowed speeds about 10 percent over the posted limit to better match the flow.
Tesla's Assisted Driving got the shortest and simplest assignment at about eight minutes. The ride was smooth, it eased off well before pedestrians and yielded to a cyclist coming up from behind. But it misread a flashing amber for a right turn, missing a specific French rule, then hit the brakes sharply instead of inching ahead with caution, which triggered a takeover. At the show, Tesla also put its Cybercab robotaxi on display, underscoring that the region is inching toward fully driverless service.

Xpeng's Navigation Guided Pilot running LO3 behaved like a model citizen. It stayed within limits, slowed for yellow lights, left room for cyclists before reds, and braked lightly before settling into a firm stop. It shifted to the side in a tunnel to let quicker traffic by, and it dealt with construction and roundabouts cleanly.
The flip side: on tighter streets it dropped below the 30 kilometer, 19 miles, cap and felt pokey. According to Xpeng, the next-generation NGP is slated for a European rollout beginning in 2027, pending regulatory approval.
The drives suggest advanced driver assistance can shoulder a lot of urban workload and reduce fatigue, even in cities where traffic is messy and rules get intricate. They also show how much tuning is needed for each place, from surprise cyclists to blocked lanes.
Tesla's supervised system is still awaiting approval in the European Union. For Chinese brands growing in Europe such as Chery, pairing advanced software with competitively priced EVs is part of the pitch, but Chery has not set a timeline and is continuing testing and validation.
On fully driverless service, Europe trails the US and China. Trials are limited to select cities, including Zagreb, where Pony.ai, Uber Technologies and Verne are operating a limited pilot that runs vehicles with no safety driver onboard. Wayve and Waymo are conducting tests in designated areas in London and Munich. Liu Xianming, who leads Xpeng's General Intelligence unit overseeing the self-driving technologies, put it this way: "The only metrics to gauge whether an autonomous driving system is successful is whether or not it fit to the local environment and whether or not local people want to use it."
The bottom line: software that can handle Paris rush hour is a selling point for any automaker, but revenue timing still rides on local approval and acceptance. Watch who gets EU clearance for supervised systems, where driverless pilots expand beyond limited runs, and which brands can adapt quickly to Europe's street-level quirks.
