Tesla actually re-introduced radar sensors in HW4. https://www.teslarati.com/tesla-hardware-4-hd-radar-first-lo...

They might not use them for autopilot, but maybe for some emergency braking stuff, when everything else failed.

Is there anyone using only cameras except Tesla?

Yes, silly using just cameras, I mean humans have Lidar sensors, that why they can drive, why didn't new just copy that....oh wait.

It all seriousness though, Tesla are producing cyber cabs now which are 10th the price of Waymo's and can drive autonomously anywhere in the world. I think we can see where this is going. (Hint: not well for Waymo)

Also the article is speculative 'MicroVision says its sensor could one day break the $100 barrier'. One day...
