How much of the American boarder with Mexico is out of radar contact?

There was some fuss about the FAA creating TFRs for the UAVs that are flying
with boarder patrol along the Mexico. Why can't the UAV just fly along
under an IFR flight plan and everyone else just avoid the little thing just
like any other plane on an IFR flight plan?
The "UAVs" are really remotely-piloted vehicles. The pilots are
instrument rated and the planes are on IFR flight plans. That info
comes from a USMC pilot of one of them.
