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.

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.

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.

They are probably confusing google auto with bluetooth.

On Android there is an option called "Bluetooth tethering - Share phone's internet connection via Bluetooth" . If it is On and you are connected to the car's bluetooth it will have internet access via your phone.

Don't get CarPlay/Android Auto that way though, so no navigation/maps for example.

Are there any cars that support CarPlay/Android Auto that don't have built-in navigation/maps?

My 2019 Subaru legacy supports auto and does not have built in navigation. The aftermarket dashboard display in my 2011 Ford ranger also supports android auto but has no built in GPS.

Cash handling isn't free, and for smaller businesses might actually end up being more expensive than accepting electronic payments.

If your margins are so razor thin that the cost of handling cash is significant, you need to raise your prices. Cash is legal tender -- not accepting it for in-person transactions is really shitty (maybe shouldn't be allowed?)

It's not about "just raise prices", it's about some industries (e.g. upstart restaurants) that already have massive failure rates and have hyper competition. Even airlines don't make money on flights, and instead only on selling credits cards or other perks.

If your operating costs are some percentage higher for accepting cash versus the coffee shop across the street that doesn't, you're more likely to fail.

I'm suspicious that the car's system can do this. I don't think we should be assuming your car can tether internet through bluetooth until we see someone snoop Toyota-bound traffic being routed through their phone.

Maybe two metal pins through the GPS and the cellular antenna coaxial cables would do the trick?

In case of Subaru turning off 2G made their modems keep trying to reconnect 24/7 draining and killing battery. Subaru refused replacing batteries killed by defective car.

On my classic cars I fitted a battery quick disconnect in the boot. Might need to start doing that with modern cars too.

Has anyone experienced a case where they needed an over-the-air safety update/recall performed, but weren't able to because they removed the cellular modem? I'd like to think failure to apply an OTA safety update would trigger a mail-out notification requesting you bring the vehicle into the dealer. But that's probably optimistic...

Its probably an antipattern on a car to need an OTA "safety" update in the first place.

The safety update is physically removing the modem IMO. Can't be wirelessly broken into if you aren't on the network to begin with.

> Even after the modem is removed, if you connect your phone to the car via Bluetooth then the car will use your phone as an internet connection and send all the same telemetry data back to Toyota. However, if you use a wired USB connection then it does not do that (see the discussion here and elsewhere), so I exclusively use CarPlay via USB. The problem with this is that both carplay and android auto capture their o…

Is there any information about precisely what vehicle telemetry they capture and retain?

I know the laws are far from perfect, but isn't there some legislation compelling them to disclose what they collect?

What specifically would be the most relevant law/regulation? (If it varies by geography, pick any major market, eg. California, that is big enough to impact their engineering design and the content of published material). You mentioned they're cagey, and my aim is to examine if there's a gap between what they're supposed to disclose and what they do, which could be rectified by litigation. Eg. If they just say "vehicle telemetry" that doesn't tell you much, and I'd happily contribute to an EFF effort to get them to elaborate.

Alternatively someone who works close to this code could provide some examples of what a "typical" smartphone OS platform collects these days.
