So far I've been impressed enough with the HW4 Teslas that I haven't had them do anything that I had to intervene to correct or prevent. It's pretty amazing at how well it handles all kinds of things - construction, weird merges, road debris. This morning, there was a tire in the middle of the road, which caused traffic ahead of me to slam to a halt. Mine had to brake hard enough that ABS engaged, and then navigated around the tire. I was impressed.

It doesn’t have to be completely unsupervised for the driver to realize huge improvements in quality of life. I don’t even notice when people drive slow or cut me off. I’m just relaxing, fiddling with the music or talking to my family. And managing two toddlers is a lot easier when my brain doesn’t have to run a constant background job.

I do hope that unsupervised comes soon though. The tech is there, or at least far enough that I consider it better than my own driving. The hurdle is regulatory now.
