This is a very good point.  I sent a DR-135 (with Tracker2) along with a
friend on a cross-country trip.  I made sure to set the keypad lock and had
no trouble with it.  Though for some reason, my old Alinco DJ-F1T will
occasionally move 5 kHz off frequency when you turn it on, despite the
f-lock being enabled.

This is an application where Bob's proportional pathing scheme would be
good.  You can get rapid updates direct, and occasional WIDE beacons for
longer range.

FRS has always disappointed me for vehicle to vehicle communications.  It
can't compete even with a 5-watt 2-meter HT with a cheap 1/4 wave magmount.
