He showed how poorly their outdated radar performed.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

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.

Sounds like “none”.

[ra7]

None what? I just gave you an example of Waymo using 4D imaging radar [1]. Aurora also uses imaging radar [2], Mobileye as well [3]. AutoX is going to start using Arbe radars. All of them are leading players in SDC industry.
