As an engineer, I see little value in removing any sensors. No matter how noisy or limited they are, they bring additional information which, if processed, could improve overall accuracy. This is commonly referred to as "sensor fusion". So this is probably is purely cost-saving move. While I understand how radar could be expensive, I am not sure the saving on much cheaper ultrasound sensors is worth the loss of additional information about the environment.
As Telsa Model 3 owner, I can attest that their automatic parking rarely works anyway. They should be adding more sensors to improve it, not remove them.

- kypro 4y agoI've worked on 3d vision systems before and have experimented using different types of sensors in multi-sensor setups, and I'd argue that overwhelmingly it's a software problem. More sensors help, but passed a point it's extremely marginal, plus you're throwing the majority of the raw data away anyway. I do agree though - assuming processing power isn't a performance bottleneck here, more data is always better. But there's a reason humans only have two eyes and not three or four, for example. Two eyes are really all you need.
- macrolime 4y agoCompletely off topic, but there's a fascinating list of animals with more than two eyes. For example the four eyed fish which uses one pair of eyes to see below water and one pair to see above water, when it's swimming along the surface. https://wildlifeinformer.com/animals-with-more-than-2-eyes/ https://wildlifeinformer.com/animals-with-more-than-2-eyes/

Unless other sensors break, then they're suddenly useful redundancy. In a safety critical product like this, that alone should preclude the removal of sensors. > But there's a reason humans only have two eyes and not three or four, for example. Two eyes are really all you need. You still get two, both for depth sensing and for redundancy; and some animals like spiders have 6-8 eyes.
- simion314 4y ago>But there's a reason humans only have two eyes You also have ears, a body that allows to move your face, your eyes can move too, and the brain has a model of the world including a model on how people thing and how would they act. So will your Tesla have some eyes that can turn and look in all directions? would look cool to have snail like eyes.
