alt Hacker NewsPhysically unlocking with NFC could be done without all the security holes.
Modern cars already make it much more difficult to lock your keys in the car than in ye olden days.
And the "did I remember to lock my car" remote-check functionality doesn't seem nearly worth the "now a hacker can remote-unlock my car" tradeoff. It's not like that "did I lock it" check helps prevent a "someone smashed the window and grabbed something out of it" scenario anyway.

It's completely unnecessary.
Modern cars automatically lock themselves when they sense there are no keys nearby, nobody in the seats, and the doors are closed for x minutes.
NFC is vulnerable to relay attacks, so newer systems are including UWB (like AirTags) where the car can confirm the distance to the key fob
