Missy Cummings: I know there’s a whole set of parents out there that are with me. I call myself Eeyore sometimes about the status of self-driving cars in the future.
What I truly want, being the mother of a 14-year-old, is for self-driving cars to be here. I don’t want my 14-year-old daughter behind the wheel of a car ever. I do research in this field. I do understand how bad human drivers are. What I want would be for this technology to work, but understanding my job is to do research in this field, I recognize that it’s not going to happen.
Seems not just cautious but really pessimistic about FSD, granted more work needs to be done, but its progressing.
This post (September 25, 2018) she mentions limitations of Radar and LiDAR, but no mention of cameras, an impression that they are not desirable or useful.
I think I know why.
Pilots are very much numbers people. They need to know how fast, how far, how long, how high, etc. Numbers.
Radar and LiDAR provide volumes of discrete data points, while a camera system might be limited to a few specified by the attention points in the field of view.
It may be that Tesla is not trying to map, but trying to "see" (and I could be wrong on that).
