Modern cars are horrible. I recently discovered that all new cars sold in the EU constantly beep at you for supposedly speeding, even though the system doesn’t work well, and it has to be turned off every time you start the car.

They beep when you go above the speed limit, and only for a couple seconds. If they do that 'constantly' the problem is in the driver's seat...
It takes two seconds to turn off in my car (though by law it has to reset on every drive), but I never bother. In situations where it's "ok" to drive a little over the limit, it's a small price to pay and a gentle reminder.
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.
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.
> They beep when you go above the speed limit, and only for a couple seconds.
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.
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.
It’s horrible since it gets the speed wrong 25% of the time and 25% of the time it beeps because you are doing 33 in a 30kmh zone because you are just going along with traffic.
When you get in a car, you have to spend 20 seconds disabling all those systems. Lane keep assist is downright dangerous as it keeps you in your lane if you do an emergency avoidance manoeuvre.
I don’t hate safety system like emergency brake assist or ABS but I don’t need a nanny keeping me in my lane. I also don’t need a coffee symbol for taking a break.
My Honda Civic gets the speed wrong almost 100% of the time in Slovenia where intersections automatically cancel out non-zoned speed limit signs (so no crossed out signs that the car could read). Luckily it doesn’t beep or nag about it.
(Which makes me wonder, is there a flag set to make it not beep on cars sold here? Cuz otherwise people would be returning them en masse)
It's the same in Poland. Toyota found a way that you can install some "immobilizer" thing that hacks the system into muting the alerts (but they still blink though) and was so proud that they started calling owners offering it for install. But all the cars do beep.
Lane assistance on hire cars piss me off. If I need to swerve I shouldn't need to be pulling against the wheel -.-
I'll raise you that.....
A completely empty straight country road with just a cyclist ahead of me. I pull out to pass the cyclist with plenty of room, and the lane assist tries to swerve me into the poor bugger. Very alarming considering I had no idea the car had such a "safety" feature.
Isn't eye tracking required there too now? If you look away, or even not in the direction the car expects, for more than a couple of seconds >> more beeps.
The car I drove from 2025 didn't have it.
