Rain fell on Plasencia as a Tesla with FSD Supervised entered the city’s oldest streets, squeezing through stone alleys that have challenged drivers for centuries. Tesla filmed the lead and released a three-minute video, testing the driver-assistance system on narrow, unpredictable city streets.
Plasencia is a tough place for any car. The Tesla started at Plaza Mayor, continued down Pedro Isidro, then turned into San Ildefonso, a stretch known locally for tight spaces and rough cobblestones. The car passed the Church of Salvador, where chipped corners show signs of past scrapes. In the video, it made it through without a scratch. Its sensors and software kept working in the rain and across the city’s twisting medieval layout.
Tesla’s 2026.27.300 release notes say FSD Supervised can start from a stop and change lanes. The system can also select exits, maneuver around objects, make turns and stop at destinations.
This wasn’t a one-time event. Tesla says its engineering fleet has spent two years on Spanish roads with FSD Supervised, logging 460,000 kilometers. The company is testing how the system handles city jams and rural roads in places like La Vera. The technology lets the car do most of the driving, but a human must always be ready to step in, but smooth things look on camera.
Spain has become a popular place to test new car technology. Manufacturers want to put their systems through their paces on the country’s varied roads and in different weather. As reported earlier, other brands are also using Spanish roads to test their latest models. The testing reflects Spain’s growing role in shaping the future of driving.
The Plasencia test brings the complications of real-world driving into view, the kind labs can’t replicate. Driving through old, crowded streets in the rain is nothing like cruising on a highway. The lead shows how FSD Supervised handles the rough edges of daily life.
Tesla North and El Nacional report that the Plasencia demonstration is part of a broader, ongoing program. Over two years, Tesla’s FSD Supervised test fleet has covered 460,000 kilometers across Spain. No official data has been released on accidents or the composition of the test fleet.
People remain basic to the process, even as the technology advances. Tesla says a driver must stay alert and ready to take over. That requirement reflects what today’s technology can and can’t do. The Plasencia lead shows the system’s progress in Spain, while making clear how much still depends on the person behind the wheel. Until cars can lead themselves, these tests examine how humans and machines can share control on the road.
