New Leaf ProPilot

Car and driver says that steering assist will only work below 31 mph if tracking a car in front of it. So as theorized above, yes auto steer will work in stop and go traffic.

As a side note, there have been a couple reviewers and online folks who try to compare the M3 to the LEAF and appear to think PP does not include steering assist, therefore must be inferior to M3 AP. From this regards the LEAF L2 PP most definitely is not. Where it lacks is the L3 lane changing ability, and AP following highway navigation. It would be a pleasant surprise if the existing hardware would at least enable simple highway navigation. I understand if lane changing would not be possible due to additional cams / sensors needed.

Not my experience at all. Pro Pilot is very able to maintain lanes from at speeds down to zero.

Some of the time anyway. It sounds like a target will have to re-acquired when either you or the car in front turns.

IOW, works like all automated driving systems.... "sometimes" oh wait!! I hear feathers getting ruffled... Lets change that to "nearly all the time"

Feel better?... Cause I don't.

The difference is relying *entirely* on the car in front like it sounds the Nissan system operates, or using the car in front as one of several inputs (like I think is true for the Tesla system.)

FWIW, I am an automated driving system skeptic and I bought my Tesla without EAP or FSD. Part of that was the cost but the other part was my opinion that systems that encourage me to hand over driving duties to the car are not a good idea. I want systems that make me a better driver. Augment, not replace. To me it is an important distinction.

For the next few days Tesla is offering Tesla owners like me the opportunity to buy AP (mostly lane keeping and radar assisted cruise control) for $2000. I'm thinking about it.

I think the tech is great for allowing you to judicially direct your attention elsewhere for a few seconds here and there and although that does not seem like much, its actually quite helpful when dealing with driver fatigue. Trusting beyond that is simply stupid. This thing about Tesla going 781,231,181 miles 1271 feet between errors resulting in fatalities might make you feel better but it does not me. It is really surprising that the Feds allow it. If Tesla was a plane, it would be grounded right now.

I generally agree with your view on current assisted driving tech. However, we probably should not compare current AP incidents with aviation. If that were the case, then all cars would be banned from the road for inflicting 30,000 deaths per year! But I get your point on how they are overselling their AP capabilities causing negligence by drivers.

I can confirm that ProPilot will function below 30 mph if you're in traffic. I live in Los Angeles and use it daily for my commute. I would say that its ability to function in stop-and-go traffic is highly dubious though. The system will force you to press the Resume button if you are stopped for more than 2ish seconds. If you have parking lot like commutes like me, this really diminishes the benefits of the driver assist capabilities, since you're trading pumping the brakes and accelerator pedals for pushing a button all the time. It's an improvement but far from the homerun feature it could be.

I'm really hoping that Nissan will offer a software upgrade to fix this, as I can't seem to figure out the rationale why manually resuming is required after stopping for 2+ seconds. What happens after 2 seconds? The car seems fully capable of continuing to apply adaptive cruise control and steering assist. If they could just fix this, I would be a super happy owner.

Oddly though, I really don't see anyone else talking about this issue. Is ProPilot just not used often by most people?

I think that the issue is the possibility of someone stopping while using PP in traffic, and getting out of the car for whatever reason, leaving it engaged. Would the car then take off alone and empty, and resume following the car ahead, or not.....?
