That's very relevant indeed - one-meter accuracy would remove the need to put any kind of 'flag' on top of a dead drop container. Without retroreflectors or etc. marking packages, broad searches of likely drop areas would not produce results worth paying for. Also buyers would have no need for a means of finding inconspicuous retroreflectors - just a 'really good' mobile phone. Still not "the perfect crime", but a much improved one. :o)
