Why Has Tesla Been Looking Into Using Radar?

No more than a year later than doing away with radar, Teslas is seeking to use a more advanced, high-resolution radar setup to improve their Full Self-Driving experience and assist their Tesla Vision software.

Even though
Tesla
owners and fans know that the company had originally planned to only use camera-based systems in their self-driving vehicles, after doing away with radar last year, it seems like Tesla could be pivoting. The recent announcement that Tesla may be looking to add radar to their cars has the industry scratching their heads. Why is Tesla looking to use radar instead of its highly-developed camera system?

Why is Tesla thinking of changing its “Tesla Vision” system? 

Tesla developed its Tesla Vision system to replace an old operating system that used radar and cameras, before shifting to the current modus operandi—no radar. But the company spent years developing its current self-driving and driving assist platform, as
Electrek
explains. It’s only been a year since Tesla did away with their old, partially radar-based detection software.
However, Musk mentioned in an interview conducted with Electrek last year that “a very high-resolution radar would be better than pure vision, but such a radar does not exist. I mean vision with high res radar would be better than pure vision.” 
So is it possible that Tesla has found a high enough resolution radar to use in combination with its vision-based object detection for improved driver assistance and self-driving capabilities? 

Tesla may have found the high-resolution radar it’s been searching for

The same article points out that Tesla has already filed with the FCC to use a new radar system in their EVs, which means that they’ve probably developed the radar technology they’ve been waiting on. 
A diagram of their FCC filing seems to show that the radar will be forward facing, similar to the old technology used before Tesla Vision. So with this in mind, the likelihood of another round of Full Self-Driving software updates seems inevitable. But what will drivers, many of whom own older generation Teslas, do if their cars can’t support the new update? 

Will owners of older Teslas enjoy the updated Full Self-Driving system?

Even though Tesla has claimed that all vehicles produced since 2016 will be able to support Full Self-Driving, that hasn’t been the case for some owners. They found out after attempting software updates that would replace the radar with Tesla-Vision that that wasn’t true. 
Because Tesla needed to update the onboard computer to support Full Self-Driving in the newer models, older Teslas weren’t able to use the new vision-based system. So even if Tesla does go back to a combination of both radar and cameras, their EVs produced before 2016 won’t be making the cut.
