Elon Musk Shares A Bit More Detail About Tesla FSD’s Pure Vision

Yesterday, Elon Musk tweeted that Tesla’s Full Self Driving (FSD) Beta V9.0 would soon be live, and that this new update would switch to pure vision with no radar. In a followup reply to @WholeMarsBlog’s request for more information about “pure vision,” Elon shared some precious nuggets of information.

When radar and vision disagree, which one do you believe? Vision has much more precision, so better to double down on vision than do sensor fusion.

Elon touched upon a common issue that could cause confusion in any smart vehicle or device that uses both radar and vision (which do you believe when they disagree?), and then noted that vision was more precise. It’s smarter to focus on vision than sensor fusion — going with the most precise and accurate option is the best for any outcome.

Tesla Owners Club of Austin also had some insights to share and Elon replied to those with more information.

Good point.

Next major software rev will do much better with automating wipers, seat heating & defrost.

Probable seat settings just based on occupant mass distribution should be possible.
