Watch Tesla Model 3 Autopilot Try To Tackle Winding Road At Speed

AUG 21 2018 BY MARK KANE 37

Tesla Autopilot keeps the Model 3 within the lane of a winding road

Scott Kubo demonstrated a 10-mile run of the Tesla Model 3 with Autopilot engaged at a decent speed of 50-60 mph on the winding state route 79.

As it turns out, the 2018.26.3 version, besides several situations when the car took all its space to the limit, was able to drive without driver intervention.

It’s still not enough to entrust Autopilot completely (or even remotely), but it’s improving and at least on well-marked roads during the day and in good weather conditions, the results are promising.

Tesla Autopilot Fast on Winding Roads – 2018.26.3

Scenic drive with plenty of curves. Autopilot driving for more than 10 miles (16 km) without driver intervention. Hands on the wheel at all times.

California State Route 79. Software version 2018.26.3. Note that this drive was under ideal weather and lighting conditions, and virtually no other cars on the road.

*It’s important to note that we aren’t promoting the improper use of Tesla Autopilot, but rather sharing this latest video of its use. It is always the driver’s responsibility to follow all of Tesla’s guidelines, keep hands on the wheel, pay attention to warnings, not exceed the speed limit, etc.

Great drive and good video.

This is my Tesla Model S with EAP tackling a Cotswold village in the UK. The car drove pretty much the whole way to our cycling trip destination as we were in traffic. I’ll edit & post the whole trip at some point but the villages are always the hardest part due to strange road markings & usually parked cars.

Pretty cool, thanks for sharing.

Where’s the windy part?

He or the car should obey the speed limit.

Agree. Safety is supposed to be a major benefit of AVs. If they speed then that’s out the window.

I thought you said “a winding road”? 😊

10:30 – 10:55 shows the software is still alpha quality and should not be released to consumers yet.

being able to stay locked in the lane centered within the lines on a well-marked road with no traffic blocking the view ahead is table stakes for competent self-driving.

That’s a scary stretch.

I’ve used AP very rarely in the past, but stopped using Autopilot completely after it killed that Apple employee on 101. The human brain can’t reliably babysit a robot, and the software is always changing in hidden ways, making it hard to predict failures until it is too late.

Yeah, I am a fan of TACC, but the autosteer is s bit iffy on all but divided highways. Hence the reason Cadillac disables Supercruise on those kind of roads.

Why is InsideEVs promoting a use of the EAP that is beyond the system’s capabilities and contrary to Tesla’s clear instructions?

“Autosteer is intended for use only on highways and limited-access roads.”
“Autosteer is particularly unlikely to operate as intended when:
• Driving on hills.
• Driving on a road that has sharp curves”

Repeat after me: Autopilot is only for use on freeways, it is not for use on highways without dividers or on roads with cross traffic or traffic lights or pedestrians. This is why people drive into parked firetrucks with EAP (Utah).

If you want to do experiments to see how products can be used in amazing ways that are contrary to manufacturer instructions, here are a few ideas for future videos:
– Riding electric bicycles on the freeway
– Driving a jet ski with no hands
– Flying kites next to power lines
– Using a blowtorch as a flashlight… in a dark gas station (trust me, works great)

We aren’t promoting anything. We are sharing a video that a driver made using Autopilot. There are tons of these videos out there and we always try to share them. I added a disclaimer to the article. Thank you for your comment.

Thank you for adding the disclaimer. EAP is not intended for the use shown in the video – when it is ready for this type of road, Tesla will let us know. Misusing the system (as this driver is doing) invites misguided regulatory intervention that will delay the adoption of safer vehicle technologies.

This “Tesla can read street signs” thing is a complete myth. It is getting the speed information from the map data, not from the signs. Sorry kids, it ain’t so.

I think cameras actually read street signs. My car (not a Tesla) tells me the posted speed limit when I enter a construction zone, which is not on any map.

Your car may, but Tesla (at least APv2) does not, in my experience. That said, I haven’t used it recently.

The discussion here is about real Tesla cars, not your imaginary one.

WRONG. My Model S changes its speed limit sign icon the instant it passes a legible speed limit sign, and if it passes an illegible sign (bent, muddy, rusty, etc) it doesn’t change. Sorry not sorry; it is so. (Still doesn’t read, or at least obey, stop signs or other signs, and never will; it’s AP1)

That turns out not to be the case, Scott. Autopilot, using onboard video cameras, can indeed read traffic signs including speed limit signs. You can see this quite clearly in the video linked below:

Yea, that’s a fail. You are expecting it to adjust the speed down because the road is curvy, its not that smart. Several of those limit excursions are concerning. I have seen the same thing on my car. This is not what the EAP is designed for at the moment.

My AP1 Model S slows down for curves all the time. When I first got the car, it didn’t even try, but after the next software update and since, it does it pretty well. So I don’t know what you’re talking about.

That was a good video. Particularly impressed with the 35mph turn at 5:10 in the video, where the car proactively slowed down before the turn. I’d like to see how some of the other cars with lane-keep assist do on the same stretch of road. I wonder when Autopilot proactively slows down before a turn vs reactively slows down. With my car, I always assume it’s reactive.

Dangerous and irresponsible and breaking the law (speeding). And stupid for posting it on public streaming.

“Auto steer is a beta product.

Autosteer is intended for use only on highways and limited-access roads.”

(⌐■_■) Trollnonymous

Isin’t this the kind of road they tell you NOT to use AP?

Steers like a drunk teenager while texting anytime there’s a curve. If I was a driver coming in the opposite direction I would be spooked enough to honk and tell you to get the hell back in your own lane. And what happens when the lane markers disappear or are obscured like on so many of these ill maintained back roads? Keep your hands on the wheel, pay attention and drive your car please.

Thats what I thought, it is beta at very best. It did not go off the road, and that is considered progress? I drove a Cadillac CT6 40 miles on the freeway and never touched the steering wheel or pedals, that was a relaxing experience, this looked more scary…

Autopilot+AutoSteer will handle 98%+ of freeway miles just fine, just like your Cadillac will. The difference is that AutoSteer will actually work on roads with two-way traffic, even if not all that well under certain circumstances, as shown here. Your Cadillac won’t even try once you exit the freeway.

Of course, some people would consider “not even trying to handle roads it can’t handle all that well” to be a feature, and not a bug. But that’s a different argument.

Looked like quite a bit of ping ponging, and not too difficult a road. Is AP now to the level of control of a 15 year old new driver?

Or a drunk?

“It’s still not enough to entrust Autopilot for 100% of the time…”

I’m a strong Tesla fan, but it is a vast overstatement, and one I think is irresponsible, to suggest that Autopilot+AutoSteer are getting close to being 100% dependable to drive the car without the human driver remaining alert and ready at all times to grab the wheel.

Everyone needs to understand this: No driver assist features in any production car, including Tesla Autopilot+AutoSteer, is designed to detect stationary obstacles when the car is traveling at high speed. That is why semi-autonomous cars — including even Tesla’s latest production cars — will run into fire trucks which are parked in the traffic lane!

Autopilot+AutoSteer is a pretty good lane-keeping feature. But it should never, ever be depended on to actually drive the car, despite what all too many “Look Ma, no hands!” videos posted to YouTube show.

The point was you can’t trust it. You can’t count on Autopilot 100% and just go to sleep. However, I changed the wording to make that even more clear.

Yeah, it’s not good enough to trust it any percent of the time. You can use it if you stay vigilant, but don’t ever trust it.

Love all thing Tesla well Elon really the best thing about this video was I wintered in SoCal this past winter and drove this highway frequently. But hands on the wheel all the time, you are a braver man than me gunga din. Thanks for the vid

Right around the 4:56 mark, it shows the autopilot is going from line to line….

I don’t know if I would trust that if there are oncoming traffic close to the center line.

Driver should have his/her hands in a better position to take over.

I am not too impressed

I’d really like to see a repeat of same route to see if the car has learned. Also a run in the dark and ideally rain (I realise this last request may take a while!). Thanks for sharing.
