Tesla Robotaxi Stops Mid-Intersection After Running a Red Light… The Influencer Onboard Calls It “Impressive” (fuelarc.com)

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?

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%.

What's the reasoning behind CVTs being the only non-manual transmissions you'd consider?

They lack the nice feel of manuals and the reliability of modern automatics. Have you tried an 8HP or 9G-Tronic? Either one will last you a long time and shift so smooth during relaxed driving that you can't tell it's going through gears.

Because the idea of keeping the engine at the ideal rev range regardless of your speed appeals to me. Gears have powerbands, CVTs are always in the sweet spot. How can you do any better than that?

Gears have powerbands, CVTs are always in the sweet spot.

Isn't that basically true of automatics with 8+ gears, too?
