Tesla FSD, or Full Self Driving technology, has hit another snag, with several drivers reporting issues. The affected drivers claim that the Level 2 ADAS in Tesla vehicles stops the vehicle too soon at certain intersections. According to The Drive, some drivers believe the reason for the sudden stop of the impacted vehicles is that the traffic signs at some intersections are larger than average.
On August 21st, a Twitter user reported this issue, stating that the vehicle slowed down much sooner than expected. The driver noticed that there was a larger sign than the usual one in the neighborhood. As he wrote, the onboard computer and ADAS system are likely interpreting the sign as closer to the car, causing the Tesla car to slow down prematurely. As he wrote, the sign was 60% larger than standard signs, and the car interpreted it as 60% closer than the actual position.
Others in the same Twitter thread contended that Tesla cars’ onboard cameras would not interpret signs and objects in this manner. Interestingly, other people have reported similar problems with their Tesla vehicles and ADAS systems. He claimed that his Tesla had mismarked several stop signs. “It used to have this issue with stopping at these stop signs because this street has giant stop signs on it,” the Tesla owner wrote, adding, “And so it would kind of try and stop a little bit too early because the stop signs were so big and I kind of realized ‘Okay, the size is a big part of how it’s kind of doing that.'”
