Waymo doesn't serve any snowy locales yet. But sure, years and years ago mapping was worse than it is today? The mapping used today is working quite well in warm weather locales.

The hardware is far from good. I have one and got real intimate with it. The battery life is ass and holding everything back (e.g. maybe why they disable touchscreen for a lot of things?). The mediatek chip inside is really cheap and bad. T

Well and the realities of bad security, bad usability with touchscreen typically disabled, crappy battery life ^^'

I think the hate directed their way has more to do with the outsized claims of the founder, Jesse Lyu. For example, he claimed that you're buying a device with a "LAM" but it turned out to be playwright scripts wrapping APIs

I'm glad you feel that way (and I mostly feel the same / ride Waymos frequently), but it doesn't change the reality that you're putting all your faith in a self-regulating company that does not cooperate with regulators

It's likely because thermal is expensive for the BOM and also wrt energy usage. Also low res.

Who’s to say what unit economics they’ve achieved but I’d hazard to guess that their investors wouldn’t support expanding their fleet and service unless the unit economics are at least close to break even. Cost for sensors and overall BOM k

No, Waymo is not driving remotely. Remote operators can only answer simple questions. They're at the point of commercialization so it's all about unit economics. There's no point in driving remotely especially since it does n

You can individually remove the discs and use a compressed air cannister, but it's very laborious.

> There are smartphone cameras that do depth sensing and HDR Depth sensing is again, estimated or using time of flight sensors which is pretty much short-range lidar. HDR is used already in AV perception, but still loses to your eyeballs

Every software release is a totally new driver. If they release software at a cadence of say, 6 or 8 weeks, would you feel comfortable riding? You don't know how safe the car was during that time -- any part of the driver can regress.

1:1 remote human monitoring would not scale from a unit economics perspective, and even if they did that, the remote operators can't drive the car, only offer small feedbacks. So the car is really driving itself. The safety story is an

Depends on what's being authored. Many times more experienced engineers review PRs from junior engineers and do have a higher level of knowledge.

This is my experience too. Just waiting for bzlmod to finally be supported by all the commonly used libraries. Looking at you, gRPC.

by kajecounterhack 2y ago
Agreed, thus the need for radar. Thermal imaging can also see past fog fwiw, though it has other tradeoffs.

Camera only perception systems don't have any indication of what is solid vs not. This is why Cruise and Waymo use LiDAR. They have exactly what you're talking about. Even then it's hard -- consider soft vegetation or trash.

Do you mean economy? Your comment doesn’t mention the environment. OP: “preventing unwanted pregnancies is good for environment” (because humans have big carbon footprint) You: “having fewer children is bad: see these economies” This read

Humane actually worked really hard to do security the right way fwiw. They have to send your queries to OpenAI etc but they aren't straight up harvesting passwords. They probably save your queries and pictures to train their models but

Same here. $200 for an artifact of the times / more or less a little piece of decoration. Occasional question answering, maybe. Definitely not hooking it up to Spotify or any personal accounts after hearing how they handle security.
