So tell me on your keyless go mechanisms

We've all seen the videos online how thieves are using the relay tactics to get entry into people's car on their drive and do this all under 90 seconds.

I want to know specific mechanisms because I have performed this test that my fiance is in the car with me and she has the key in her bag. She gets out to go to the shops while I wait in the car, the car complains and doesn't allow me to do anything but switch off.
If there was such a relay attack to my car, I can see how they would mimic my key using the relay attack to get into the car and start it up but when they are out of range aka drive off down the street, would my car no detect there is no key present and then become unusable?

Do other keyless cars behave the same or once the car starts it will continue running and operate regardless if key is present or not? Just curious to know if manufactures have done much to counter the theft problem.

On a Merc you just double tap the lock button to disable keyless go broadcasting.

To answer the OP, if you're driving along and throw the key out of the window the car will continue to drive as normal. You'll get all the notifications popping up to say 'key not present' etc, but nothing will prevent the car from functioning correctly until you turn the engine off. Then you'll be unable to restart it.
I think i saw a clip a youtube someone demonstrating what happens when they throw the key out while driving. Can't say i saw it but it appeared in my feed one day. Need to find it to know what exactly happens. If it doesn't do anything to stop the car from functioning and just a warning light then its pritty much pointless to the theives.
 
I've seen a perticular Lexus model where thieves are exploiting the CANBUS via the headlight on the drivers side, they pull apart the fender to get access to the wire, tap into it and then drive away. They say if this Lexus is seen driving at night with only one headlight, chances it was taken off the driveway of someone's house.

It goes to show, I've heard people's attitude where if its been stolen they dont want anything to do with it even if there are chances of it being protected in someway. What would you do?
 
At the end of the day, high value cars are either put in a shipping container and off to another continent or broken into pieces to be sold on the 2nd hand market.
Driving around in a stolen car causes more suspicion and there are so many identifiers which need work to remove its original identity.

My car has a manufacture built tracker through the app, it can be tracked to an degree but if its in a lead box it wont be transmitting any signal plus the thieves are smart enough to disconnect the battery.
