Tesla has REMOVED Radar from Model 3 & Y

[davemilke]

My view is to go all-in on vision. The cost savings are a non-issue for me.
What some may call the 'benefit' of redundancy, I would call putting too many cooks in technical kitchen - a kludge.

My thing is simple: I love that the little interface shows all the cars around you and can even see like 2 or 3 cars ahead! I think when the radar system goes, it won’t be able to see multiple cars ahead anymore.

Also, if the two cars ahead of the car that is in front of you crash, Tesla won’t be able to read them anymore. I’ve seen videos where Tesla cars go “beep beep beep” indicating a danger like 3 seconds before the crash happens and it’s something 2 cars ahead that only a radar could detect.

Not sure if this type of feature will go. But if I only see the car ahead of me and the ones beside me, I’m gonna be sad that my interface got a downgrade.

I'm sure 1 million engineers considered this

Wasn't radar the main cause of the phantom breaking?

[sithsiri]

If I remember correctly their problem was radar’s tendency to see some things and not see other things was causing more problems than it would without radar at all

[devindykstra]

I thought for sure they would wait until after the radar-less FSD beta (9.0) was tested before they dropped the radar. I hope that's coming soon. I really want to see what Tesla has been able to improve.

It comes down to how much you can trust the various inputs. The radar is useful as a secondary system if you trust it enough to over-ride what the cameras are telling you. Having more information is not always useful.

It doesn't even matter if there are specific times when the radar provides better information than the cameras unless you can know for sure you are in one of those times.

Wonder how it would have handled the downpour rain while I was driving 70 mph and couldn't 10 feet in front of me. I felt safe with a follow distance of 7 cars and autopilot handled it like a champ.

Rainy day. Foggy morning. Direct sunlight.. good luck.

Why do you want a sensor that can see in the fog or night ? If visibility is not good enough, the car must slow down, or find a safe park. The fact than humans often drive when they should not does not mean an autonomous car should. FSD mean no human intervention, but it does not mean that the car cannot give up. I would be quite ok with a car saying "Sorry, not safe, no FSD, continue by yourself if you think you have superpowers". However I agree that in a 100% visual approach, the visual sensors must be "good enough" and without blind spot. Of course, in 50 years, when everything on the road will be autonomous, it will be quite different, with car communicating all the time, communicating with the infrastructure. Etc. Then driving will not be anymore based on vision.

Multi-sensor corollation or Sensor fusion is not that easy. Cross corollation mistakes can lead to serious errors. Range is good with the radar however angular accuracy of the radar both in AZ and EL is much less resolution than the visual sensor. The neutral net visually can resolve and identity objects, the radar can't. Apparently Tesla sees it advantage in eliminating the radar.

[ianbladuell]

So will Tesla send a software update to deactivate the sensors for any prior model 3/y they have been built and are out on the road now?

[medericlagace]

How will it perform during snowstorm if the cameras can't see ahead? The radar was the only one to "see" through snow cloud and trigerred the emergency braking right?

[audreymcneal]

I ordered a Tesla earlier this month in person at the store, but am planning on getting a test drive vehicle, so it should already be built and have radar, I assume, as I am taking delivery in the time frame mentioned in the blog, but my car is already built, somewhere. And I’m glad! If they want to not use radar as a factor in FSD at a later date, whatever, but in the transition period, there will of course be issues. I don’t mind the redundancy of having it at all.

[chickenchopfriedrice]

should you drive when fog is too dense?

[rgeraldalexander]

Sorry to hear this. I'd still appreciate having radar on my Tesla for all the situations you've mentioned.

[MrIbernie]

I drive with vision all the time in my 2008 Tundra. Works great! If we needed radar to navigate our surroundings then God would have given us Radar. Bats and Dolphins use sonar that the tesla's still have. Everyone calm down it will be ok.

[rare_wubbox]

Yes we want and need redundacy. So several cameras is a superior ide..
Tesla has tested a lot and found its better and safer without radar👍🇳🇴

[matthewboyd]

I think Tesla had a lidar setup to actually configure/test how good pure vision is.

Also they still have the ultrasonic sensors so it's not exactly pure vision.

Love the new Mac 😯😯😯 love the white bezels
