It's a fair point, but if we're taking about cars, I'd say physical access is a given. Keyless vehicles haven't quite enabled remote car thefts just yet
I’d also like to point out that most modern vehicles use rolling codes to prevent replay attacks. I’ve only recently learned this as I was concerned about devices like the Flipper making these sorts of techniques to people that otherwise would lack the expertise to put such a device together themselves
They can also take into account the time it takes to travel from the request to the response so if you're 2x the distance away with a relay that somehow works in the middle, it would take too long and be rejected.
