Tesla Model Y: Limitations and Inaccuracies
Speed Assist may not be fully functional or may provide
inaccurate information in these situations:
- Visibility is poor and speed limit signs are not clearly
visible (due to heavy rain, snow, fog, etc.).
- Bright light (such as from oncoming headlights or
direct sunlight) is interfering with the view of the
camera(s).
- Model Y is being driven very close to a vehicle in
front of it which is blocking the view of the
camera(s).
- The windshield is obstructing the view of the
camera(s) (fogged over, dirty, covered by a sticker,
etc.).
- Speed limit signs are concealed by objects.
- The speed limits stored in the map database are
incorrect or outdated.
- Model Y is being driven in an area where GPS or map
data is not available or where speed limit signs can
not be detected.
- Traffic signs do not conform to standard recognizable
formats.
- A road or a speed limit has recently changed.
WARNING: The list above does not represent an
exhaustive list of situations that may interfere with
proper operation of Speed Assist. Speed Assist
may fail to provide warnings for many other
reasons.
