would be nice if the vehicle allowed you to drive off even if it didn't detect the keyfob (as it does now with comfort access) ....but it would continuosly scan for the keyfob while the vehicle is in motion and if it didn't detect it within a minute or so it would slow down the vehicle and shut it off leaving it stranded on the side of the road...

would've been a great "anti-car jacking" solution for those with comfort access..

only problem is what happens when you have it in your pocket but the battery is weak or dead??

the keyfob in the comfort access option is not rechargeable...
