Consumer Reports Slams Tesla's Navigate on Autopilot Update, Calls System 'Far Less Competent' Than a Human Driver

consumer reports slams teslas navigate on autopilot update calls system 8216 far

In this writer’s opinion, one of the greatest things to happen to high-speed motoring is the blind spot monitoring system. Try as we might to religiously check our mirrors and peer over our shoulders before each lane change, there’ll always be that time we half-ass it, just as an unseen car creeps up in the shadow of our B- or C-pillar. BSM can be a savior.

However, handing over the entire lane-change process to a combination of software and sensors, at least in Tesla vehicles, is far, far worse than doing it yourself, Consumer Reports claims. After giving the latest update to Tesla’s “Navigate on Autopilot” feature a shakedown cruise on the highways of Connecticut, the consumer advocacy group handed the system a failing grade.

The automaker rolled out an update to its Navigate on Autopilot feature in early April, claiming the system, which debuted in October 2018 and allowed Tesla vehicles to change lanes after a turn-signal prompt from the driver, to dispense with the bag of flesh and bones behind the wheel entirely. Only buyers who paid extra for Enhanced Autopilot or the misleading Full Self-Driving Capability gain the feature.

With the update, drivers can set the system to automatically change lanes when a destination point has been entered into the car’s navigation system. It can also be set to turn on automatically whenever a driver inputs a destination, rather than ask for permission each time. Hitting the turn signal stalk will defeat the looming lane change.

While drivers can choose to be notified of an impending lane change via audio, visual signals, or a wheel shaker, this would, in the minds of many tech-hungry drivers, defeat the purpose of having such a system. If you’re already checking your blind spots to ensure the computer isn’t making a mistake, why not just signal and move the wheel while you’re at it?

Out on the highway, Consumer Reports’ Model 3 test car reportedly behaved like BMW 3 Series, cutting off cars and passing on the right.

“As a result, the driver often had to prevent the system from making poor decisions,” CR stated. Once again, if you have to babysit your advanced driver-assist feature, what good is it to the driver?

“The system’s role should be to help the driver, but the way this technology is deployed, it’s the other way around,” said Jake Fisher, Consumer Reports’ senior director of auto testing. “It’s incredibly nearsighted. It doesn’t appear to react to brake lights or turn signals, it can’t anticipate what other drivers will do, and as a result, you constantly have to be one step ahead of it.”

The update made the test car no less erratic than when it was tested with the original Navigate in November, CR said. Even then, “it lagged behind a human driver’s abilities in more complex driving scenarios despite Tesla’s claim that it would make driving ‘more relaxing, enjoyable and fun.'”

Recall, too, that Tesla claims it will have fully self-driving cars by the end of the year.

In rolling out the April update, the automaker said drivers have already traveled “more than 66 million miles using the feature, and more than 9 million suggested lane changes have been successfully executed with the feature in use.” It isn’t known in how many instances a vehicle approaching from the rear had to brake hard to avoid hitting the slower Tesla that just appeared in its lane.

Consumer Reports’ roast of the company’s latest tech update will surely lead to another round of the on-again, off-again Tesla-CR boxing match.

    The tragic thing is, Level 2 automation, if *actaully* sold and operated like that, is a *wonderful* driving tool. I use the LKAS and ACC on my '17 CR-V every time I'm on the highway. The adaptive cruise and lane-keeping functions handle all the short-distance chores that are boring and fatiguing, while my senses can pay more attention to the things the computer is incapable of, like spotting a distant 18-wheeler on an entrance ramp, a crappy driver weaving out of their lane, or a traffic jam coming up in a few hundred yards.

      What about crappy drivers randomly speeding up and slowing down in their own lane?

    If Elon announced it you can count on the fact that: 1) it will take at least twice as long to reach the market as he says, 2) it will work half as well (or less) than he announces, 3) it will be 20 to 50% more expensive than he predicts, and 4) it will lose money.

      If we're talking full level 5: "1) it will take at least twice as long to reach the market as he says" I think that's overly optimistic. I'd say 5 times longer. 2) it will work half as well (or less) than he announces Yeah, that's a safe bet. Maybe a bit optimistic. 3) it will be 20 to 50% more expensive than he predicts, Probably. That's a safe estimate. and 4) it will lose money. Probably.

  • Nrd515 Usually for me it's been Arby's for pretty much forever, except when the one near my house dosed me with food poisoning twice in about a year. Both times were horrible, but the second time was just so terrible it's up near the top of my medical horror stories, and I have a few of those. Obviously, I never went to that one again. I'm still pissed at Arby's for dropping Potato Cakes, and Culver's is truly better anyway. It will be Arby's fish for my "cheat day", when I eat what I want. No tartar sauce and no lettuce on mine, please. And if I get a fish and a French Dip & Swiss? Keep the Swiss, and the dip, too salty. Just the meat and the bread for me, thanks. The odds are about 25% that they will screw one or both of them up and I will have to drive through again to get replacement sandwiches. Culver's seems to get my order right many times in a row, but if I hurry and don't check my order, that's when it's screwed up and garbage to me. My best friend lives on Starbucks coffee. I don't understand coffee's appeal at all. Both my sister and I hate anything it's in. It's like green peppers, they ruin everything they touch. About the only things I hate more than coffee are most condiments, ranked from most hated to..who cares..[list=1][*]Tartar sauce. Just thinking about it makes me smell it in my head. A nod to Ranch here too. Disgusting. [/*][*]Mayo. JEEEEZUS! WTF?[/*][*]Ketchup. Sweet puke tasting sludge. On my fries? Salt. [/*][*]Mustard. Yikes. Brown, yellow, whatever, it's just awful.[/*][*]Pickles. Just ruin it from the pickle juice. No. [/*][*]Horsey, Secret, whatever sauce. Gross. [/*][*]American Cheese. American Sleeze. Any cheese, I don't want it.[/*][*]Shredded lettuce. I don't hate it, but it's warm and what's the point?[/*][*]Raw onion. Totally OK, but not something I really want. Grilled onions is a whole nother thing, I WANT those on a burger.[/*][*]Any of that "juice" that Subway and other sandwich places want to put on. NO, HELL NO! Actually, move this up to #5.

  • SPPPP It seems like a really nice car that's just still trying to find its customer.
  • MRF 95 T-Bird I owned an 87 Thunderbird aka the second generation aero bird. It was a fine driving comfortable and very reliable car. Quite underrated compared to the GM G-body mid sized coupes since unlike them they had rack and pinion steering and struts on all four wheels plus fuel injection which GM was a bit late to the game on their mid and full sized cars. When I sold it I considered a Mark VII LSC which like many had its trouble prone air suspension deleted and replaced with coils and struts. Instead I went for a MN-12 Thunderbird.
  • SCE to AUX Somebody got the bill of material mixed up and never caught it.Maybe the stud was for a different version (like the 4xe) which might use a different fuel tank.
  • Inside Looking Out Scandinavian design costs only $600? I mean the furniture.
