I've rented an Audi in Germany. On autobahns with 140 km/h speed limits there are lots of signs that limit speed to some low values like 50 km/h, but only under some conditions like snow, darkness, workday morning etc. Of course the car had no idea about those, started beeping for no reason and once even decided to do an emergency brake.

No. They beep when they think I go above the speed limit.

Technically it is wrong 100% of time because the car underreports the speed. But even if we agree to ignore that fact, it is still wrong constantly because the car doesn't have nearly enough sensors and compute power to actually figure out what's the limit at the moment.

Thus this feature is as useful as cookie banners.

The car probably doesn't have perfect knowledge of speed limits across Europe.

The car reads the speed limit signs too, they don't just rely on GPS.

In some countries the speed limit can change without a explicit sign (speed limits cancelling out at intersections / changes in pavement, etc.). In my experience, in multiple instances the systems offered a speed limit that is higher than the actual one, which can be dangerous if you're just blindly trusting the clanker

The signs also seem to take priority over GPS, I was on a road with a 50mph speed limit tonight and the car read something it thought was a 20mph speed limit sign. I have the beeps disabled but it still displays the red 20mph sign on the dash to let me know it thinks I'm breaking the law.

from the last rental I had, they're not good at that.

Why wouldn’t they?

Dataset is readily available for most places. Pull local on entry to jurisdiction on every drive…

Have you ever actually worked with geodata in depth? It's a wall-to-wall nightmare.

Never for production at scale admittedly, only for research and on fixed line connections, mostly public transport related. Some datasets are better than others.

Internet connected options here in Australia generally have good speed limit data but there are generally very few variable speed limits that allow you to travel faster than usual.

Transition is never perfect but surely regulation would account for that?

I genuinely don’t know but to me it’s an interesting problem.

Lick the boot more.

If you can't drive into a tree at 200mph and kill yourself in a car, then I do not what it.
