I should add, by the way, that while Teslas have onboard radar, it is not a primary sensor, but a secondary discriminating sensor.

This was admitted by Musk on Twitter following the fatal crash in Florida: https://twitter.com/elonmusk/status/748625979271045121

It was a secondary discriminating sensor, but the latest Autopilot 8 upgrade retasks radar to be "a primary control sensor without requiring the camera to confirm visual image recognition": https://www.tesla.com/blog/upgrading-autopilot-seeing-world-...

Indeed. And I absolutely do not trust them on it. Their radar hardware just isn't good enough to reliably do that.

Ditto. It also seems strange to be able to retask their radar from secondary to primary control.
