How are people applying enough force in NOA steering?

[Fernand]

I think voice would be a good way to confirm when needed.
When it shows lane change to follow navigation
you say "Cool", or "Go, mofo!" or just "Yeah".

Anybody see this? in 2017? OK, a prototype, but wow!

So they got like a gazillion dollars o' stuff on the roof?

Still think it looks like a coffee-maker on wheels.

 

[Fernand]

Oh, the dashcam captured my second swerve into the shoulder
and I sent Tesla the actual location with the Request Help feedback.

This happened at that spot once before, but I thought I'd done
something wrong, like disengaged NOA. Not. Probably an error in
the navigation database telling the car there's a lane here. It's
probably reproducible, so some brave soul could go drive there
to answer the $64,000 question: "and what would have happened
next?"

I don't blame Nicki, it's tough being a semi-smart car.

Worst case that $64,000 prize should cover the totaled vehicle,
with an upgrade to full FSD - get that puppy a bigger brain.

I put my left or right hand at the bottom of the steering wheel against the vertical post.

I have had no problem with the system detecting my hand, even when it is relaxed on the wheel. Before NOA I held the steering wheel the same way with AP and it worked great.

That right lane line is not very solid. Not surprised the car thought it could cross.

Plus, we need to see the markings from before it shifted...

 

[Fernand]

I don't think that explains or justifies it, lines are never perfect. I have no idea if it's a map error or other problem, and I'm not bashing Tesla. But there's good reason to keep a hand on the wheel, this all happens very fast, and anyone who's not paying attention is being dumb.

Your wish is my command. Here's the lane change sequence. What's significant and that you can't notice from the stills, or even during the first few video replays, is to what degree it's like one sweeping lane change all the way into the shoulder (or the ditch).

 

[Fernand]

And the repeater videos show nothing I can see that it would be trying to avoid.

 

[Fernand]

I want to make it clear that I had the bad luck of running into two similar anomalies in one day after months of pretty excellent NOA. I've had a problem in NOA around this location before, so it's either a very specific "boundary condition" they need to analyze, or there's an error in the Navigation map, and I sure hope Tesla corrects it soon.

Two questions. A tiny medicine sized baggie with BBs,
attached with a black velcro strip at the junction of the
wheel and a spoke. Easy to drop off. @scottysize said
12 grams. Any disadvantage to a bit more? 28 grams?
Has anyone checked whether it changes with the
steering mode setting "sport" <-> "comfort" ?

 

[Fernand]

Well, 28 grams there didn't work at all.
Does it have to be on the right hand side?
Or the side where your hand rests?

 

[Fernand]

And I should clarify that I do NOT want to take
my hand(s) off the wheel. It's the need to keep
watching for the blue warning and have to jerk
the wheel (and risk disengaging AS) that's the
problem. When I hold the wheel it's not enough,
it complains. It's actually more tiring than plain
driving.

As others have said, hanging a hand at 5 or 7 o’clock works just fine.

Even if you took your hands off the wheel and get the blue warning, you should NEVER have to jerk the wheel, you have plenty of time to apply slight rotational pressure with no risk of disengaging AP. The blue warning lasts for like 30 seconds and then it starts to do an audible warning in which you have another 30(?) seconds before AP disengages. No need to rush it, just apply gentle rotational pressure.

 

[Fernand]

I'm dense or spastic or something, but I can't get
the hang of it, and I'm much better off with a 90g
counterweight on the wheel. I'm not defeating the
intent, as it will still blue nag if I take my hand off
the wheel. Works for me. I don't want to double
post, but I had a close call tonight, take a look here

Don't take your hands off the wheel

It is 12 oz not 12 grams.

Mine works 100% of the time with 12 oz, my friends works 80% of the time with 12 oz. So might need a little more in some cases.

 

[Fernand]

I was looking for that magical equilibrium, and at 90 grams,
which is around 3.2 Oz, right where the spoke joins the wheel,
I can let other people drive and they will still have to rest a hand
on the wheel, but nothing more, no special moves or resistance.

It depends where you attach it. At 12 Oz, or 340 grams, you'd have
to place the weight pretty far in, close to the hub, to ever see a nag.

Since the SC replaced my whole steering unit (needlessly) I think
it's not that mine is in some way unusual. It's how people normally
hold the wheel, apparently, and I could never get it right without the
counterweight.

And BTW, after more experience, I believe that the incident that
I reported above in post 62 & 66 above was due to the AP/NOA
disengaging due to my own jerking on the wheel as the car started
into the lane change.

 

[Fernand]

Need to get a black NagBag (tm). Good thing I don't have to look at it.

I repeat, with 90g of BBs, a bit over 3 Oz, it's not to defeat the hand on
wheel requirement, which is there for a reason, just make it smoother
to work with, no need to jerk. Works for me anyway.
