I recently took my Tesla Model Y, equipped with Full Self-Driving (Supervised) v14.3.3, for a 150-mile drive on the Pennsylvania Turnpike to put the system through a real-world stress test. There were plenty of good moments, but also a few bad ones. Overall, however, I was impressed by Full Self-Driving.
The good moments
On the motorway, FSD drove with confidence. The lane-keeping assist worked precisely, and the vehicle changed lanes autonomously to overtake slow-moving traffic. The response to roadworks was particularly impressive: the system recognised the temporary road markings and adjusted the speed in good time. Merging onto the motorway also went smoothly.The bad moments
In complex traffic situations, such as partially obscured junctions, the system sometimes hesitated. On one occasion, it braked abruptly when a lorry cut in from the adjacent lane – it felt unsafe, even though the reaction was correct. FSD also struggled in heavy rain: the cameras got wet and the system temporarily deactivated itself.[IMPORTANT] > The test shows that FSD is already very reliable on motorways, but there is still room for improvement in urban environments and in bad weather. For European users hoping for approval, this provides insight into the current state of affairs.
