This Tesla Robotaxi demo video is a mess.

Watch as the car makes a left turn from the wrong lane, ignoring a red light. The safety operator steps in, and the car comes to a stop… right in the middle of the intersection.

Eventually, it completes the illegal turn after blocking traffic for 45 seconds, which raises the question, what exactly is the safety operator there for?

Not related to self driving, but other shitty car design.

I had a Nissan with a CVT before it was widely known they were garbage. I hit the brakes to avoid someone that ran a red, and the CVT went in to some protection mode and left me and my family stuck in the middle of the intersection for 2 entire light cycles before it'd move again.

Dealership just kept saying it's fine and it was protecting the CVT from damage after going from throttle to brake quickly. I don't give a fuck about the CVT, I care about the squishy bits inside the cabin.

After it did that again and the power windows stopped working the same day, I traded it in for a Mazda with a proper transmission. 248k miles later it's still great.

Damn shame that CVTs are so janky because it's the only non-manual transmission I'd consider. But reliable CVTs that don't do fake shifts are hard to come by.

The eCVT in my wife's Ford C-Max is an absolute dream. It's so smooth and helps the car take off much faster from a stop than my 350Z, despite having 100 less BHP. Nothing beats the feeling you get from immediate torque when you don't have to wait for the revs to build. Problem is that it also has a 75% failure rate after 100K miles. She's at 120K now and it's still going strong, so she was in the lucky 25%.

Must also be pretty hard on the tires

Can't say I've noticed a difference. The tires wear at a normal rate. The traction and stability systems are very good in this car, despite it being over a decade old at this point. Wheel spin is well-controlled.

Nissan CVT has had its fair share of bad press, but CVTs in general are good to go, and more specifically, Toyota's CVT is a good piece of gear. I don't doubt your story, but it's got me real curious about what the issue is. I can't imagine a scenario where hard braking somehow disables the car, but I know "safety features" in abundance are a thing.

Yeah they apparently ran some scans on the transmission and everything checked out.

The 2nd time I drove straight back to the dealership since I was nearby and they scanned again without shutting the car off and still showed no issue. All I know is it'd act like it was in neutral for about 2 minutes. Then it'd barely creep forward even at 4000 rpm. Going to park and back to drive didn't help. Restarting the car didn't help. After about 10 minutes of slowly getting better, it'd be back to normal.
