Earlier quoted context omitted.
Does such car exist? (Tesla Maybe?)
None of the cars I have driven in the last decade had physical keys. Owned a Nissan, Mercedes and Toyota, rented various BMWs, Peugeots etc...
Because besides personal experience, googling the proximity keys of all of those brands shows the expected pop-out keys.
Also photos of various models from all those brands in 2020 show key holes on the driver's door, which would suggest there is in fact a key somewhere that fits it.
