No worries
My safety score dropped to 98 after it says I did “hard braking” and “aggressive turning”. I managed to get it back up to 99, but I’m driving extremely carefully even for me, and this is getting to be a bit much.
FCW = Forward Collision Warning
NOA = Navigate on Autopilot
SAE = Society of Automotive Engineers
The SAE set a series of levels for automobile automation and defined what each level would be, numbered 1 through 5 (or 0 through 5, with 0 being no automation at all).
Level 1 is shared control of the vehicle between the driver and computer. Cruise control is an example: you control the steering wheel, computer controls the gas/brake.
Level 2 is full control of the vehicle by the computer, but constant driver attention is required and intervention may be called for at any moment. This is Tesla’s Autopilot. FSD is also currently level 2, but should be progressing to a higher level at some point.
Level 3 is full control of the vehicle by the computer and constant monitoring is not required. The vehicle may not be able to handle all situations, but it won’t require immediate driver intervention to prevent a dangerous situation. For example, some edge case not foreseen in its programming confuses it, so it notifies the driver to take over. If the driver does not, it will safely park itself. This is where FSD is headed.
Level 4 is full control of the vehicle by the computer and no driver intervention is ever required. It can handle everything that ever happens on the road. The catch is that it can only do this within a specific area e.g. Waymo’s driverless taxis which only operate in Phoenix, AZ (the Waymo taxis aren’t truly level 4 since remote drivers are still occasionally called on to handle edge cases. This makes it more like level 3 with geofencing, which doesn’t neatly fit into any SAE level).
Level 5 is total control by the computer anywhere. No human intervention ever required. Just tell it where to go and it goes there.
I don’t think Tesla refers directly to the SAE standards in terms of promising customers this or that level of autonomy. But they have used the levels in technical descriptions such as to regulatory bodies like the California DMV. Elon Musk has also been directly asked at presentations if the FSD features he’s referring to were SAE level 5 and he said “yes” (incredibly dumb thing to say IMO).
