I saw a Waymo in Seattle, today. If Waymo can get Seattle right, that gives me a lot of confidence that their stack is very capable of difficult road conditions.

Note: I have not had the pleasure of riding in one yet, but from what my friend in SJ says, it’s very convenient and confidence-inspiring.

I have had the pleasure of riding a few times in SanFrancisco.

The drive was delightful and felt really safe. It handled the SF terrain, traffic and mixed traffic like trams very well.

I wouldnt trust a self driving tesla ( or any camera only systems) though!

I took the Waymo from San Jose airport to home on the peninsula. It took the 101 highway back for the most part, driving very conservatively at 65-55 mph, and in the right most lane. It still has a few quirks though. When there aren't any cars around it will speed up to 65 mph, but at on-ramps, it will slow down to 55 and then speed up once past. It will get stuck behind slow drivers being in the right most lane and patiently follow them a few car length behind them. On the plus side, the lidar stack field of view as shown on the internal display seems to see pretty far down the highway.

> laser pulses

> phased-array

I'm not well versed into RF physics. I had the feeling that light-wave coherency in lasers had to be created at a single source (or amplified as it passes by). That's the first time I hear about phased-array lasers.

Can someone knowledgeable chime in on this?

Interesting to see the cost curve drop ... this always changes the market.

I have been watching the sensor space for a while. Cheap LIDAR units could open up weird DIY uses and not just cars. ALSO regulatory and mapping integration will matter. I tried to work with public datasets and it's messy. The hardware is only one part! BUT it's exciting to see multiple vendors in the space. Competition might push vendors to refine the software stack as well as the hardware. HOWEVER I'm keeping an eye on how these systems handle edge cases in bad weather. I don't think we have seen enough data yet...
