Tesla’s recent move to remove Radar in favor of a camera-based approach to autopilot and fully autonomous driving aligned with company plans and statements in recent revenue calls For CEO Elon Musk The goal was to move away from radar and rely on camera systems for Tesla’s autonomous driving plan, but some owners are not convinced with the move. Over the past few days, I have received several emails and tweets regarding the decision, with some owners still not fully confident in the vision-based approach Tesla will take.
During the Q1 2021 earnings call just a few months ago, Elon Musk made it clear that Tesla will be switching to a camera-based system for AP and FSD. Comparing cameras to human eyes, Musk’s explanation made a lot of sense.
“When your vision works, it works better than the best human because it’s like having eight cameras, it’s like having eyes behind the head, next to the head, and having three eyes of different focal lengths to the side. ‘before. It is – and processing it at superhuman speed. There is no doubt in my mind that with a pure vision solution we can make a car that is considerably safer than the average person.

Now the point is that the eyes, while excellent at seeing things in the clear, are very effective, and it makes perfect sense to try and use this type of approach for autonomous driving, as it makes sense. is how humans have driven for years. But when humans are faced with low visibility and extreme weather conditions on the road, confidence decreases and many drivers adjust by driving at lower speeds. Some even stop and wait for the weather to calm down, which is rare for many, but some just don’t like driving in bad weather.
This is where radar comes in handy as it can identify and locate objects and how far away they are from the vehicle in low visibility on the road, which human eyes or cameras simply cannot do.
An email from an Australian reader seemed to restrict this point even further. A man named Peter emailed me and said his Model 3 recently identified a truck that was in front of him but hidden in a white, opaque haze with several car links in front of his vehicle. “I assumed the visualization was created using radar. Under these conditions, the message of multiple blocked or obstructed cameras appeared and the autopilot screamed and recovered, ”said Peter.

He then added: “On several other occasions, I noticed on the display screen an unseen vehicle obstructed by an SUV in front of me.”
Without radar, recognition of these vehicles would not be possible, raising some concern among drivers who have used the radar system in vehicles to gain confidence in their surroundings.
Now, in a somewhat comical response to the concerns, Musk posted a Reddit response from u / YukonBurger, which said they were working a lot with radar and were “very, very happy” with Tesla’s decision. He basically explains that it’s extremely difficult to try to combine radar and cameras, and there are cases where using your eyes is just a better option because you can see how far away you are from things. Interestingly, the publication admits that “radar is only really good for low visibility situations where lane keeping is also likely to be degraded enough not to be worth it.” He concluded by stating that the vision is still fast enough to avoid accidents or vehicles in front of the car in a short period of time, the real problem is with the cars behind you.

It seems that the real key to seeing being a better approach is that under clear conditions he will have no problem identifying himself and removing himself from danger. Even in rainy conditions, where visibility is not necessarily bad, the vision approach is more advantageous than the use of radar.
The point, ultimately, is to make cars act like a human would, and humans don’t have radar. Instead, they compensate for reduced visibility with less dangerous driving. Slower speeds, more careful navigation and less frequent lane changes. Autopilot and FSD are shy and “shy” enough to begin with, it’s not like they’re driving like pissed off teenagers.
I think, while this decision is somewhat worrying for some drivers, the pros outweigh the cons. It’s been part of the plan for quite some time, and I think now it’s becoming a reality, some are starting to piece together the pieces that there won’t be radar so visibility limitations could end up being problematic. I wouldn’t worry, as I believe cars will adapt just like humans, they’ll just be more careful and courteous on the roads in these settings.
