I'm wary of self-driving systems based only on cameras. He should really wait until cheap LiDARs are available in a few years.

- cameldrv 10y agoThe comma only works on a few (maybe just one) Honda car that has a built-in front facing radar that they're able to tap into. With that, comma is using roughly the same sensor package as the V1 Tesla autopilot.
- empraptor 10y agoThanks. I didn't know Comma One also uses front facing radar. Do you happen to know what state of the art millimeter wave radars are capable of? I found some references from 2013 about Panasonic product with resolution of 20cm, but maybe there are better options now?
- striking 10y agoLIDAR is still not that good for driving. It's better than cameras but it's still pretty bad, because its vision can be obscured by weather conditions. Radar is the gold standard for vision like this. That being said, I thought they were using radar.
- empraptor 10y agoEDIT: cameldrv pointed out in a reply to my original comment that Comma One uses its cameras and also taps into the vehicle's existing front facing radar. I was thinking of something like Quanergy's solid state LiDAR. I know the planned $100 version is probably a few years out, but it seems promising. And there are other companies/institutions working on cheap LiDARs that work in bad weather. Following link is of a talk Quanergy CEO gave at Stanford. https://www.youtube.com/watch?v=uPqzo29Q9Wc https://www.youtube.com/watch?v=uPqzo29Q9Wc
