Or just wait until ADAS front assist gets a false positive around a t junction and someone stops in your rear.
I mean … following too closely gets you liability for the collision and typically a citation.
Regardless, it doesn’t help when the car is damaged and there was no reason for aeb to kick in. The computer thought it was right but it wasn’t.
Why does the automobile industry insist on keeping these things in-house when they are clearly terrible at them? I recall an interview with a Ford manager a few years back where they were asked something about adopting Car Play and the response was something like “we have people that can write software for us, so we won’t be using that.”
Money. Why give that up when the customer is really only going to use bluetooth audio anyway? Anyone who cares enough about navigation is gonna use an app on their phone. Native car navigation is a superficial value-feature not a use feature. The edge that Carplay gets is really minimal. I'm repulsed by the new car market, its many multiples over-connected anyway. When it comes to digital features my gut says only th…
I thought the same thing until I owned an EV. Using the car's navigation is essential for road trips that involve charging along the way. Maybe some day Google Maps et al. will gain access to API's to read the car's current charge and enough information to accurately predict charge along the route, but for now I have completely changed away from using 3rd party nav and rely only on the native vehicle nav.

I keep an atlas in my back seat just to be safe now.
“In China, Mercedes-Benz is engaging in a local cloud partnership with Tencent to support its automated driving systems. An enriched UI for automated driving functions including an advanced lane-level map view is planned.” Tencent, really? How did that come about?
The real question for me is what does an ADAS system rely on the cloud for? Hopefully nothing in real time.

Some Mercedes also have the bug where the sign classifiers somewhat regularly mis-read 80 as 60 for speed limits, causing cruise control to arbitrarily slam on the brakes in some parts of the country. You would think that they would catch these things with rudimentary quality control. The automotive code for many of these systems is incomprehensibly awful but the entire process of how it is made virtually guarantees…
I just borrowed a Tesla Model 3 that stopped for green lights. I asked a service person: apparently it is known to stop for a green light if there is no car ahead. The display shows a green light, a red line, and fine print saying that the car will stop for traffic control.

But they are not a software company at the core. They need to be to pull this off.
Both Mercedes and Volkswagen have absolutely massive software divisions, easily 10k+ people. They pay really well for German standards and have access to a large talent pool of people that would like to live in Germany.
I just found this presentation with technical details: https://group.mercedes-benz.com/dokumente/investoren/praesen... I guess it is not a typical OS, but more like a collection of tools that build on already existing OSs. This is comparable to ROS (Robotic Operating System), which are just some programs, middleware, services and conventions to build software for robots on Linux. It seems like this should integrate a…

> Cruise will also disengage in heavy rain or snow That’s what it should do, honestly. It’s not safe to drive with cruise control in low traction conditions.
This is one unconscious bias from California-based self-driving companies: weather conditions worse than overcast skies exist in other parts of the world. Recently, I drove in a whiteout blizzard with huge flakes without much accumulation on the road. Road was drivable, but I couldn’t see road markings. The experience would have been less scary with some sort of augmented display to show the road borders.

Like what’s the highest quality luxury brand now, Lexus? Given that it’s Toyota engineering behind it I’d assume they are still good but I’ve never been in that market so idk.
Still those three, plus Lexus, Infiniti, Acura, Range Rover etc.

Hydroplaning/sliding is a real risk, but you can mitigate that by simply understanding how your vehicle behaves and paying attention. Sudden, unexpected change in engine RPM, you should probably cancel cruise control. Weird torquing on the steering wheel, disengage cruise and steer by hand.
