We go on a few different drives every year through some mountain ranges (not off-roading)... there are always areas where our phone and the XM radio go out (haven't taken the Tesla on these drives as of yet)... so there would be times for us when we would be in trouble had we pulled over on the side of the road to take some pics and then not be able to restart the vehicle without the key.not wanting to be the lowest rung on the ladder - I'll segway back on topic.
FOB'less driving is only a bad idea if/when you end up in an area with skuzzy phone coverage. Not such a big deal in major areas - but we've been on the boonies where we'd have to go to another state just to get coverage. Thankyou T-mobile for a paltry 5 gig's of data in Montana ... where you don't even exist.
