Modern day fob hacking is done through repeaters that are live hacks and not something someone is going to be able to do by simply following you to your car and making a clone like the old days. Rolling codes killed the old clone methods. These days someone walks up to your home at night, scans for an active fob broadcast signal and relays that back to the guy sitting next to your car so that the "live" signal is read by the car and it opens and will start. They would have to have a trailer setup nearby since you're car is going to auto disable itself obviously once the initial repeater is no longer sending that broadcast from the fob.
So a few things...
A.) No ones using this technology to get you in a parking lot since fobs only broadcast a couple feet and you're probably going to notice the sweaty guy standing on top of you while you're loading your milk in the back, not to mention his buddy standing next to your door.. at that point they may as well just rob you, why bother with the expensive repeater technology.
B.) Most modern vehicles now have protection against these types of ranged attacks by automatically putting your fobs into low power mode when movement hasn't been detected so that people who for some reason hang their keys right next to the front door arn't so easily hacked.
C.) If you're really worried about it spend a few bucks on a Faraday bag and call it a day.
