    Source: Drivers quickly learn to skirt limits set by partial automation systems

    . . .
    In the second study, a different group of IIHS and AgeLab researchers examined how the driving behavior of 14 people who had never used Tesla’s Autopilot or any other partial automation system changed over a month of driving a 2020 Tesla Model 3. Unlike the Volvo study, this one focused on how often the drivers triggered the system’s initial attention reminders, escalated warnings and emergency slowdown and lockout procedures.
    . . .
    In total, the volunteers drove a little more than 12,000 miles with Autopilot engaged. During that time, they triggered 3,858 attention-related warnings from the partial automation system. About half of those alerts occurred when they had at least one hand on the steering wheel but were apparently not moving it enough to satisfy the torque sensor.

    Most warnings didn’t proceed beyond the initial attention reminder, and, on average, the drivers responded to the alert within about three seconds (usually by nudging the steering wheel). In 72 instances, however, the driver didn’t respond fast enough to prevent the alerts from escalating. Remarkably, 16 of these escalations — 12 of them from one driver and four from three others — persisted through the entire sequence to result in the driver being locked out of the system.

    seems like a good idea to help protect the innocent from reckless behavior

    Is more nags really the solution? Maybe a stern letter from their respective DMV would be better than more drivers ignoring the increasing invasive computer warnings. This seems to be a case of doing the same thing over and over again - expecting a different result. There is such a thing as alarm fatigue...
    There needs to be consequences for non-compliance: ie. three strikes rule. First warning, Second warning that function will be disabled if not corrected, third warning - disabling function. The function will be disabled and won't re-enable unless the car is shut-downed for at least 30 minutes. This forces the driver to re-evaluate and/or take a rest break (penalty box), before continuing the journey - if they want that function reactivated for that journey.
    One bad apple can spoil the entire bushel - why should everyone else pay for the single non-conformist?

    Just my 2-cents...

    This makes no sense. The vast majority of the time, if I read it correctly, the driver got a warning when they actually had a hand on the wheel but were failing to tug on it hard enough or often enough. This rotational tug is not a normal driving action in most cases, especially when just driving on a mostly straight highway.
    But, in any case this doesn't matter anyway since Tesla made this only one of two ways to show you are paying attention. A few months ago they sent an update that uses the in cabin camera to check that you are looking at the road.

    My most recent experience with Full Self Driving nags:
    • Five strikes (per instructions)
      • Each strike disables dynamic cruise control and lane keeping
      • Stop car, open and close door, resets to enable FSD
    • Fifth strike disable FSD for ~10 days (may be shorter)
    The "eyes on road" nag is too quick when navigating. However, FSD nag is binary between steering-input or eyes-on-road. Wearing sunglasses or UV protecting safety glasses forces "steering-input" mode.

    you mean if you have your hands on the wheel with your vr goggles on, you're okay?

    You've proven my point, more nags isn't the solution - the problem needs to be solved another way.
    ie. of the 16 violations 12 was from one driver alone - probably the guy going down a straight highway - but we don't know that because we're only looking at the computers' data point of view.
    BTW, that's why I've turned-off my lane keep assist. I don't need a faulty system constantly telling me what to do with the erroneous data the CPU is interpreting.

    yeah, lane keep assist is worthless on the 2.5 version, along with radar cruise

    They work well in my experience.

    Me too. I use it as a copilot, and it makes driving much easier. What I do is that I set it to 57 mph (actual speed) and adjust my driving speed with the gas pedal. That way, I get automatic lane tracing and automatic distance control. It is almost like self-driving, but of course, I always monitor the road and keep my hands on the steering wheel. Any kind of ADAS will take time to get used to it, and now, I find my copilot indispensable. I'm sure TSS 3.0 is even better, but I prefer no car payments to getting a Gen 5, even though I would upgrade to a Gen 5 if money wasn't an issue.

    that's great. unfortunately, ours ping pongs from line to line, and radar cruise floors the accelerator when the car in front of me changes lanes, and slams the brakes when a car pulls in.

    Well, I use it as a copilot; so, ping-ponging is not an issue, as I am still the main steerer.

    Hmm, I have never ever had the brakes being slammed when a car pulls in front of me. I don't know whether that's a bad thing or good thing though, as I can't comment because I haven't experienced it. I am usually worried that when a car pulls in front of me, I need to take control and the system won't slow down in time.

    I have the sudden acceleration when the slow vehicle clears my lane as well, which is a bit unnerving.

    So, Gen 5 owners, how does the DRCC/LTA work in your case?

    around here, lane changing (sans blinker) is very common, so it's just easier to turn everything off.
    i would hope that as radar and cameras are refined, the software would be able to speed and slow the car as well or better than a human.
    of course, there is always the possibility of necessary brake slamming.

    About lane keep assist:
    In my 2017 Prius Prime, it would take two, hands-off, nudges to cross lane lines and head off the road. Is that still the case?

    The lane assist had no Proportional Integral Derivative (PID) control logic so by the second or third nudge, the car was headed to either one of the shoulders. The absence of PID in the lane keep assist was a major fault leading to my trading the Prius Prime for a Tesla.

    Your 2017 Prius Prime came with TSS-P, which didn't even have lane-tracing capability. My 2021 came with TSS 2.0, which has lane-tracing capability. 2023 and 2024 come with TSS 3.0, which should have somewhat improved lane-tracing capability over TSS 2.0.

    For different reasons, we agree.

    Today, I can't afford to drive a Prius compared to my EV and PHEV. At most, I'm burning about one gallon per year in the BMW i3-REx, 60-90 day, in the 10-15 minute, engine warmup and operational maintenance cycles. My two cars are about 1/3d the cost per mile than my last Prius and I drive a lot of miles.

    It depends on where you live. Here in California, for 100 miles, it costs $8.77 at $5/gal to fuel a Prius LE HEV (57 mpg EPA rated) vs. $8.93 at $0.35/kWh for a Model 3 RWD BEV (132 mpge / 33.705 kWh/mpge = 3.92 mi/kWh EPA rated). So, it is about the same here.

    I understand good Prius Friend @bisco has similar rates in New England area, Massacusetts. Alabama Power, South of Huntsville, recently created a dual-rate system for late night charging. But Huntsville is under Tennessee Valley Administration (TVA) which used to have but no longer offers time-of-day or even utility managed, discount rates.

    My initial examination shows Huntsville is the local utility provider from TVA. Via e-mail, both point the finger at the other. So I'll write the same letter to each with a copies to Huntsville City, Madison County, Alabama Utility Commission, Governor's office, Congress Critters, Presidential and one campaign. The outline:
    • We need some sort of EV charging, discount rate. Cite example solutions.
    • Plead retired engineer and former Marine trying to survive by driving his electric vehicle (EV).
    • Technical advantages: (1) keep base generators running with a managed load; (2) question commitment to clean air and; (3) sustainable energy.
    Sometimes, a well crafted complaint can help the reluctant to change.

    I don't think we need a discounted EV charging rate. California and new england rates represent poor regulation, with high volume rates to discourage consumption instead of building cheaper new plants and infrastructure. Texas also has poor regulation favoring old inefficient plants that are not weatherized versus new plants that are more efficient and can handle more cold and heat and and the increased population.

    I believe most users in california can get much lower rates for charging.
