A Korean Owner's 56-Minute HW3 Test of FSD v14.2 Lite Shows Smoother Highways and Familiar Limits

A South Korean owner has posted a 56-minute test of FSD (Supervised) v14.2 Lite on a Hardware 3 Model 3, describing smoother highway driving alongside moments that still needed a human input, Tesla North reported.

Owner and Tesla watcher Tsla Chan posted the drive on Nov. 10 after receiving the update that day, saying he had spent about two hours driving with it in a 2022 Model 3 RWD equipped with Tesla's older Hardware 3 computer, the site reported. His early impressions point to improvements over v14.1 Lite, including quicker decisions, better highway speed relative to surrounding traffic and a fix for a rightward steering pull he had noticed when stopping.

Those are one driver's initial observations, not a controlled comparison or an official Tesla changelog. Chan's accompanying notes also describe moments that still needed help. He used the accelerator near a tollgate and during a hesitant unprotected left turn. At the destination, he said the car's parking remained poor, leaving it straddling a lane line, and that his car still lacked a park-on-arrival option, Tesla North reported. Chan's original post stressed that more testing is needed. Neither post establishes how widely this build has reached Korean owners.

The distinction between hardware and region matters if you are comparing videos. Lite is the version tailored to Tesla's older driving computer, which has followed a different software path from newer Hardware 4 cars. The Korean test follows an earlier v14.1 Lite rollout to Hardware 3 vehicles in South Korea, Tesla North reported. In the United States, Tesla had already started delivering v14.3 Lite for Hardware 3 in October's 2026.33.5 update. Current U.S. customer firmware, as of mid-November coverage, is FSD Supervised v14.3.13 on Hardware 4 and v14.3 Lite on Hardware 3 in 2026.38.5.12. Chan's Korean v14.2 Lite test should therefore be read as a regional owner report, rather than an announcement of Tesla's newest version everywhere, or a sign that U.S. Hardware 3 cars have moved backward.

For Hardware 3 owners, the useful part of the video is seeing how the Lite software behaves in ordinary situations, from highway traffic to the final approach to a destination. A smoother highway drive can be welcome without being proof that every difficult junction or parking maneuver is solved. FSD remains supervised driver assistance. Tesla says its currently enabled features require an attentive driver who can intervene, and do not make the vehicle autonomous. Software, hardware and regional differences can also change which features a particular car offers.

If you drive a Hardware 3 Tesla in South Korea, the question this report can actually answer is narrow: one owner received v14.2 Lite on Nov. 10 and described both smoother highway behavior and interventions at a tollgate, an unprotected left and parking. It does not tell U.S. owners that a new Lite build is on the way, and it does not replace Tesla's own release notes.
