If you exit the vehicle with it running, someone else can get in and drive off, and the disabling of the starter does not occur until the can is shut off and there is an attempt to restart it the next time. Is there a way to update the software so that if the FOB was not detected it would disable the vehicle if someone tried to put it in drive? This would enhance the anti-theft effectiveness of the keyless system - no Fob, no go - the car would become disabled until the FOB was detected again.
