Perhaps we need to tamp down our expectations which are very high based on the belief that AP2 hardware should be capable of full self driving and software should be as well by now.
I think we need to bare in mind what is actually printed in the owner’s manual. From that perspective, I believe Autopilot performs as expected.
Excerpts from Model S Owner’s Manual:
Restricted Speed
Autosteer is intended for use on freeways and highways where access is limited by entry and exit ramps. When using Autosteer on residential roads, a road without a center divider, or a road where access is not limited, Autosteer limits the driving speed. The maximum driving speed is calculated based on the detected speed limit plus 5 mph (10 km/h). In situations where the speed limit cannot be detected, speed is limited to 45 mph (70 km/h). When Autosteer is engaged in these situations, it reduces your driving speed and your set speed to be within these limits. You can manually accelerate to exceed the limited speed, but when you release the accelerator pedal, Autosteer slows Model S to the limited speed. When you leave the road, or disengage Autosteer by using the steering wheel, you can increase your set speed again, if desired.
Limitations
Autosteer is particularly unlikely to operate as intended in the following situations:
• Autosteer is unable to accurately determine lane markings due to poor visibility (heavy rain, snow, fog, etc.), or an obstructed, covered, or damaged camera or sensor.
• When driving on hills.
• When approaching a toll booth.
• The road has sharp curves or is
excessively rough.
• Bright light (such as direct sunlight) is
interfering with the camera's view.
• The sensors are a ected by other
electrical equipment or devices that generate ultrasonic waves.
Warning: Many unforeseen circumstances can impair the operation of Autosteer. Always keep this in mind and remember that as a result, Autosteer may not steer Model S appropriately. Always drive attentively and be prepared to take immediate action.
