Mercedes-Benz beats Tesla for California's approval of automated driving tech​

Obviously there will now again be the argument: "but look aat that system's limitations". In my personal opinion it's better to have a system that allows you to have the car drive itself with some limitations rather than one by a manufacturer who makes all sorts of bold promises and then fails to deliver on them.

Agreed.

Some think just because it’s L3, the L2 is taken away.

The L2 is still there when the parameters for L3 are not met such as 40 MPH.

Thus, in L3, you don't get nagging alerts. When L3 conditions are not met, it would fall back to L2 with nagging alerts just like now.

It's an improvement over present liability: drivers must pay for damages if the present L2 hits an obstacle at all speeds. Now, with L3, Mercedes pays for damages during the L3"s operation. Yes, limited only to L3 but it’s better than nothing.

In the future, the L3 speed can increase to 80 mph when Mercedes is ready (70 in this article):

No it does not. Mercedes made it clear it never automatically falls back to a lower level. If L3 needs to disengage, it will disengage completely. This is to avoid mode confusion. The driver can make the car go up in levels (L0 to L1 to L2 to L3) but the car will not go down in levels.

No nag means L3. No driver intervention needed.

When L3 parameters are no longer met, nags will start automatically. Nags means L2 and human interaction needed. If human refuses to do a counter-torque on the steering wheel in response to the nag, the car shuts down.

So it does go from no nag mode to nagging mode automatically.

What that means is shifting the liability to humans is also automatic.

The human driver was enjoying texting with both hands on the phone in L3 without any nags from the system and that is fine because Mercedes will pay if the car collides with an obstacle.

However, when the nags start and humans refuses to take over and the car hits an obstacle, it's no longer L3, it's no longer Mercedes liability. It's automatically humans liability in L2 nagging scenario.

With more thinking. I now agree with you.

The fall back is not automatic just like in a purposefully manual lane change in FSD, the driver then has to manually turn the autosteer back on. After a manual lane change, the Autosteer does not come back automatically.

That is happening with Mercedes L3: once the nags start, driver has to manually shut the L3 off, only then driver can turn on L2 when L3 are not met >40mph.

I was going to rebut you other point, but it seems you saw what I meant. When L3 reaches the end of what it can handle, it is shut off completely, the driver then has to manually turn L2 back on if they want partial automation. The way you characterized it before, you were suggesting it automatically falls back down to L2 mode from L3, but it doesn't.

The nag BTW is not an indicator of L2 or L3. But definition, L3 vehicles notify the driver when it is approaching conditions it can't handle (and it requires the drive to eventually respond), which means a nag. The difference is with L3 you get a delay, so you don't have to pay attention directly, but you still need to be available to respond. As such you can NOT sleep in a L3 vehicle. The only activities allowed are ones the system can still get you to respond within a few seconds.
