It won't be scud running Dick. My opinion is that there will instead be a lot of "Unofficial" IFR flying by pilots who are allegedly flying VFR. Their aircraft have everything for IFR flight except the magic box. This is potentially lethal because some will fly VFR but others are going to fly "augmented" (nude, nudge, wink, wink) VFR.
I've heard Third hand that a bit of this is happening already.
To put that another way, there will be people who arrive at certain airstrips in crappy weather who will then tell you with a straight face (and maybe a wink) that they got there under VFR. The "mis-educational" effect of this is likely to kill young inexperienced pilots who reason that if "X" can successfully fly VFR today from A to B then I can too. I cannot put that conclusion too strongly, that type of assumption (if he can do it, I can do it) almost killed me as an Eighteen year old, when I had had my car driving licence for Two weeks..
