A lot of smart key cars are vulnerable to relay attacks. It's not a solved security issue by any means.
Nobody is fucking doing that, though! This isn’t a “oh I will hack this person using a relay attack” attack, it’s some dumb kids breaking into cars using physical measures. They are NOT going to be using a RELAY ATTACK
Challenge Accepted
They are. It’s not incredibly common, but it’s not rare.
My coworker had his car stolen from his driveway. He believes it was a relay attack.
That being said, it’s super easy to mitigate by putting your keys in a metal bin.
AFAIK they're not anymore vulnerable than central locking systems
Yes they are, because keyless listens to the car asking for authorization, so you can amplify the car signal hoping the key is not too far off, and unlock the car without any other work.
