Dude, you're so far lost. I have a good friend who's a cop. If I told him that there was a kid trapped in a car and gave him a fifteen foot estimate of where it was, he'd be in exactly the same boat as if I told him where it was to the inch. Cops made assumptions and a kid died. It's not a satellite problem.
And I'm not hopping up and down about 11.3, it still has issues. My X has been more reliable than others, but in theory, they're all identical.
In the same light, for cycling, I use a Garmin that triangulates from GPS and GLONASS for more accuracy. No reason a car or phone can't use the same technology, it's only money.
