My brother had his car (a sleek AUDI) stolen in front of his house. He left the key in the entry hall, and someone extended the range. Are current electronics (the consumer ones) good enough at scale to limit the time the round-trip car-key-car takes?

I am curious if any Teslas have ever been stolen by being able to duplicate the Tesla key. Is app + Bluetooth or the NFC cards inherently more secure than traditional key fobs?

An app can embark all modern authentication and encryption systems. You can easily secure the exchange, like we do for web today.

I imagine that the car companies either had strong hardware constraints in the key fob, or no security competency, or no interest in investing there.

The laptop in the second picture looks very nice. Thinkpad? Anyone knows what model this is?

How does that work? Once they have driven 100m what happens?

Usually it’s just to gain entry without setting off the alarm. Then a keyfob is made using OBD. Either in the driveway or 100m away if the vehicle so permits without an existing key.

Earlier quoted context omitted.

ID.7 is the most sold EV model in EU so "not total crap" is an interesting definition. Other ID models are selling well too

What's your source? it's the 5th in this ranking I found: https://autovista24.autovistagroup.com/news/europes-best-sel...

Eh, it was Germany this year: https://www.goingelectric.de/zulassungszahlen/2025/Februar/

Still, 5th is far from "eh" - on a test drive it ended up quite a nice Passat level car.

Electric cars are theft proof. No car thief would steal an electric car.

Why wouldn't they steal an electric car? The batteries are valuable, the electric motors are valuable, body panels and other parts are valuable. Most stolen cars aren't sold as-is, they are chopped up for parts and sold as pieces.
