My daily driver has a GPS navagation system and the error I'm told is closer
to 100 yards when the sytem is crunching raw data. However the onboard
computer compares the raw position to the road map and as turns are made the
position is locked in tighter and tighter. Most times, position is with in
about 10 yards.
The problem with this type of speed control is on modern computer controlled
cars cutting the fuel pump would cause the system to go lean and post bogus
fault codes in the engine computer So the goverment would have a choice, do
they control speed and screw the enviroment, or do we take care of the
enviroment, and speed on?
History seems to indicate that speeding is safe....
