That is magnitudes more detail. Millimetric?Secondly Radar resolution has gotten better. Waymo for example uses 4D high resolution imaging radar.
In comparison to Tesla's current radar which gives 400 points per second, Waymo and Mobileye's next gen radar give you around 500k points per second.
That's 500k vs 400 in radar resolution. That's over 1250x times more resolution.
What is price difference between the RADAR units?
