I know exactly what you mean. I will admit at 20mph over the speed limit going over a poorly maintained curve on the Mass Pike I usually just disengage for a moment and then switch it back on. It can take the curve, but it doesn’t feel good to let it.

I’ve had it lose tracking on the highway. It just leaves the wheel in the last position and beeps very urgently to let you know to take over.

I find autopilot helps me become more aware and less fatigued while driving. It’s a level 2 system. There is never a question of losing engagement as an active driver like what happens with level 3 self driving.

It will keep a clearly marked lane better than I can (it’s very precise with staying in the exact middle of the lane and doesn’t cut corner like humans tend to). For stop and go traffic it’s a blessing.

It sucks at zipper merging. I’ve had to brake for merging cars more than once, even though they are visible coming into my lane on the HID. That part needs work. And I don’t really trust it to change lanes as I feel like the blind spot detection isn’t quite there either.

All said it’s pretty much the most amazing driving tech ever, and the TM3 is most definitely the most amazing driving machine I’ve ever had the pleasure of owning. Just orders of magnitude better handling than I realized was possible. Curves rated at 25mph that I used to take at 45mph in my Infiniti previously with some tire squeal, it can silently tear through at 65mph. I don’t know what the skidpad rating is, but it feels unflappable and body roll is just nonexistent.

Actually it’s a bit tricky because you literally feel no complaints or judder or roll all the way up to pulling 100% of traction the tires have to offer. It is quite well mannered once it does start drifting though.

Sorry, sorry, I can’t help it. You can guess I’m thrilling at parties.




I rave about how awesome it is too. In stop and go traffic it’s wonderful and rarely asks me to touch the wheel. I don’t like it for lane changing either so I always take over.

Anyone have experience with the lower Westchester County section of the Taconic Parkway? There are some serious curves, and the lanes are very narrow. In the left lane, you're maybe 2-3 feet from the box-beam center divider.


I just saw someone reverse their TM3 into their garage with their phone. Pretty neat! Definitely will be my next car to make my long commute bearable via autopilot tech.


The ratings on corners (at least in Australia) are rated based on visibility, not some complicated traction calculation.

They factor how far a head you can see, and how much time you need to react. Lots of cars/bikes can obviously tear through them faster. But that means they are just taking much more risk.

That said, perhaps auto driving can respond quicker, but I’d imagine that doesn’t change most of those ratings give. The time needed to avoid accidents is largely due to physics not reaction speed.
