I get it, he’s trying to do everything in software (with the existing cameras), since software is “cheap” and can do anything in theory.

Unfortunately they keep showing how they’re in over their head with some of these features (like FSD). But it’s fine because their customers agree to keep beta testing while they figure things out on production cars.

TBH, I hate auto wipers and have always believed them to be a tech solution looking for a problem. Never once have I been in rainy weather and thought "gee, what should I do?". I currently have a car with auto wipers (I'm not sure but I think they use the "standard" infrared sensor to detect rain) and I find them worse than manual, intermittent wipers in every way. I think the biggest problem is that the wipers tend…

> the car doesn't let me control the speed for intermittent wipers manually

What's the manufacturer? I'm in the market for a new car, and this would be an instant deal-breaker.

It feels to me like another one of Elon's stubborn whims. Sometimes these result in great innovations, like Tesla's giant car part 'gigacasting'. Other times, they result in deciding to rename Twitter "X" and forcing a team of engineers to spend over a year combing meticulously through the codebase to remove all references to "twitter.com"

This just sounds like you bought a crappy car. There are great implementations of auto wipers available in the wild.

Earlier quoted context omitted.

Isn't gigacasting awful for the consumer? Can't replace most parts, have to replace the expensive gigacast?

It's not like it's cheap to repair frame damage in any car.

Refering to this stuff, not sure what you're getting at

Autowiper sensors are some of the simplest, well understood technology around. You place an infrared led at a low angle to the windshield, you place an ir collector so the light from the LED hits it. (Remember that at shallow angles, light reflects off glass.) When water is on the sensor, the angle of refraction and reflection change, and the ir collector suddenly sees much less light. Two components, plus a microcon…

there is a hugely important implied assumption here - that the size of the water droplets are large enough for refraction to be detected. Any place with frequent drizzles or mists, these rain detectors do not work well or reliably.

not doubting you but how does it take a year to remove twitter references?

surely twitter has some internal code search tool like Sourcegraph which would let them easily search for all variations of “twitter”, right? /twi?t*e?r/gi

Elon’s belief that humans doing it with vision is proof it can be done with video

Vision would make sense... if the cameras were placed back where the driver actually sits.

And if you could rapidly move the cameras in multiple dimensions.

I think they falsely believe human only needs one sense to navigate: sight. But we actually use our hearing, smell, and touch too. So, multiple type sensors is actually better than only one.

I imagine smell and touch are less valuable when driving a vehicle.
