Your are right. We were starting to go from healthy debate to non-constructive territory. Sorry about that.
As you pointed out, there is a lot of confusion on the levels of autonomy. It’s worth getting rid of some of that confusion in this EV forum.
The levels of autonomy are well defined by the Society of Automotive Engineers and is fairly straightforward.
- L1: Partial control. Human partially in control. Car does some of acceleration, brake, lane centering, but not all. Example: Automatic cruise control.
- L2: Eyes-on. Car has full control. Human must monitor constantly and instantly override the car.
- L3: Eyes-off driver. Human does not need to pay attention. However, human must be in the driver’s seat and be able to take control when prompted by the system.
- L4: No driver, constrained. Car is fully autonomous in geofenced areas and under specific conditions. Human is a passenger.
- L5: No driver, everywhere. Car self-drives everywhere and in any environment.
There is huge variation within a category, especially in L2. Lucid Air DDPro, Lucid Gravity DDPro2, Ford BlueCruise,GM SuperCruise, Tesla FSD, etc. vary wildly in capability, yet are all eyes-on L2. This is why we are seeing vaguely defined and informal L2+ L2++ L2+++, and where most of the confusion lies.
Also, cars may have different levels under different conditions. For example, most systems are L2 on highways in good weather, but not in cities or poor weather. Tesla FSD one of the few that is L2 (however many + symbols you want to add to it) in cities. Waymo is L4 but only in select cities and conditions. The San Francisco blackout is where Waymo spectacularly failed. If Waymo was L3 with a remote human driver ready to take control, the human would have taken over when requested by the system and it wouldn’t have made the news.
Many companies are trying for eyes-off L3 on highway, where the driver is effectively a passenger and can watch videos. Those system will probably be L2 in the city. We’ll then be looking at cars with L2/L3 designation.
I hope this helps in getting to a common understanding and “language” as we talk about self-driving for Lucid.
