When did Tesla stop using radar?
What happened? In a newly released Support article entitled, “Transitioning to Tesla Vision,” Tesla explained that beginning with May 2021 deliveries, radar will be removed from new Model 3 and Model Y cars sold in North America (US and Canada). The Model S and Model X are unaffected.
Is Tesla vision better than radar?
WholeMarsBlog tweeted that when he tried it on the highway for the first time, it was even better than the radar fusion system. He mentioned smoother lane changes due to the vehicle not just tracking what the front radar would be bouncing off of. Wow. Just tried pure vision on the highway for the first time.
