Interesting as always, though an interview with Elon Musk on the topic of "The Future You" that doesn't discuss Neuralink in any depth is incomplete. :)

I can see mass reduction being plausible, but perhaps marginal. I don't see how a groove does anything good for rigidity. It doesn't widen the section. Would it be easier to make with this groove? I don't know, but since it's cast I would've guessed the opposite. The only other reason I can...

This flaw isn't unique to Tesla's Slipstream design; I've seen the same problem on certain factory rims for the Mercedes AMG, for example. "Mercedes did it too" doesn't really excuse having such a seemingly daft design feature though. Is there any advantage to having a groove there?

To be fair, washing isn't the only way to encounter liquid water in subzero conditions. If water can collect in there and stay long enough to freeze when the car is stationary, I would also consider that a design flaw.

You really are missing the point entirely.

Loading from dynamic pressure is not an exact analogy. Not even close.

Aircraft control might not be a good analogy here. Steering torque directly tells the driver how hard the contact patch is working and how far forward the stick/slide transition has moved as you approach breakaway. There isn't a directly equivalent feedback in aircraft control.

Reliability aside, there's one thing steer by wire doesn't do well that is intrinsic to mechanical steering: Feedback. I can see this becoming less important as people with actual driving skill become less commonplace, but for now it's going to be an unwelcome change for many.

I saw that at the time and wondered why they aren't just using a conventional robot arm.

The local police tweeted about it; driver was inebriated. Nothing to do with Autopilot. BCH Road Policing on Twitter

I'd ask everyone who says "product" rules out Tesla Vision/AP2 to consider the following: Autonomy is a product if you sell it to other vehicle manufacturers. (That includes fleet learning, which could become an ongoing revenue stream.) Autonomy enables the mobility service, which is also a...

Next project: Dual motor refit.

Michelin Crossclimate is great by most accounts, but yes, not yet available to fit anything larger than 225/40 R18. They have been slowly expanding the range, so perhaps next time? :) As for regular all-season tyres or winter tyres, neither of those make much sense in the UK. For most of our...

I'd guess Powerwall 2. It's also about time for Firmware 8.
