But I have never used this feature in all the time I have had it because you should not leave children or pets in a car for so long that you have to set the periameter alarm!
That is just not safe or humane.
Whether you would or would not, that's what the button is for, or maybe so you can leave your windows down while you have your car dead-locked & alarmed.
Whether you would leave you kid in the car could depend on how long it's just taken you to get the
little brat love of your life to sleep. I do know where you're coming from though. Mine are now nearly 19 & 20 but they have been left asleep in the car when they were very little, but have been watched from the house for when they woke up.
Years ago the brother of a very good friend left their twin daughters asleep in their Metro at the back of their parent shop (private enclosed court yard). A few minutes after they'd parked up, said brother went outside to check up on his girls to find the car in flames. Fortunately the actual flames hadn't yet crossed the bulkhead, but the interior was starting to fill will smoke. In this case all ended happily, but had he been just another few minutes later in checking them, the ending might well have not been a happy one.
PS your Senator had the same feature, only the equivalent of the button with the man running was at the top of the driver's sdie B post.
