Generally, testing in production is a bad idea or strictly forbidden at some companies. But the definition of Beta testing is basically just that.
A week ago, on a post-rainy, sunny afternoon, I sat in the passenger seat to see the Tesla Full Self-Driving mode Beta in action, and I give it a 5 out of 10.
It needs a lot of babysitting and absolutely can’t handle wet, shiny streets when there’s glare from the afternoon sun.
It fully blew through a stop sign that came up too fast right after turning a corner, and surprised us with a few sudden and aborted lane changes around traffic lights and construction zones.
Nearly mowed down some barricades at a merge.
Nice when it works well, but that’s limited to ideal conditions.
