You have fallen victim to the trap that this video so perfectly laid out for you. Tesla used the mmWave radar that has been in cars forever since it's a good way to do emergency braking and things like adaptive cruise control, particularly when you are a new company and you need these capabilities on your luxury sedan from day one. Now that they are much further along in their FSD efforts, they realize this mmWave radar isn't very helpful anymore. Cool, but nobody else was using it to begin with. LIDAR is totally and utterly different sensor technology.

Didn't Andrej show examples of emergency braking and how poorly radar performed v. vision?

[ra7]

He showed how poorly their outdated radar performed. The rest of the industry uses newer, vastly superior radars.

[sumnuyungi]

What radar did Tesla use? What does the rest of the industry use?

[ra7]

They are using Continental 2D radars from 2014. The rest of the SDC industry uses what is called 4D high resolution imaging radars. That's why Teslas have poor performance like phantom braking under bridges.

What models on the market use 4D imaging radars? All info I can find shows products releases in the past 1-2 years for future vehicles.

https://arberobotics.com/product/ is one. It was rumored Tesla themselves wanted to use Arbe radars, but evidently they have ditched the plan and gone radar less. I think AutoX from China is planning to use Arbe as well.

Waymo has its own custom developed 4D imaging radar and I imagine most of the other SDC players have their own versions.
