As I understand it, the roll out of 8.0 enhances the radar use to a scanning mode to build up a 3D model of the world it sees in a very similar way to LIDAR operation but at radar frequencies, this now includes the ability to "see" stationary objects. Damn clever stuff for sure.
Initially with v8.0 the radar is now running in this mode to acquire data that is sent back to the mothership to generate a whitelist of radar reflections from road signs, bridges and other stationary objects.
At this stage though, the changes to AP have not been implemented to work with this new use of the radar, precisely because of unwanted false detection events with the resultant bucketload of complaints about false braking.
Tesla have not stated when the new mode will become active, (I guess 8.1 at the end of the year?) however there are some points to consider when it does go active
- presumably it cannot go active on all roads at once - some may not have sufficient previous data
- how does the driver then know if the AP is in standard mode or "advanced" mode and will this be indicated to the driver?
-What if there is an obstruction under say a bridge ( I am reminded of the rear end shunt when a driver collided with a van at the edge of the road close to a bridge). If the whitelist is gps based then it might not be able to detect this, if it is data based and for example could subtract just the bridge "image" then surely this is a ton of data.
-if the whitelist data is large, then Tesla will have to ration what the car receives to the local area, what if you go outside of this area on a trip? What if you have no mobile signal to obtain updated datasets?
No doubt Tesla have this all thought through, I am curious nonetheless
