My GPS navigator has an unusual affinity for the Inner City Bypass. I believe it was designed that way to avoid driving through the inner city if possible. The problem is that the higher weight given to the ICB also means paths that go near it also get sucked in, as if by gravity. Yesterday morning Deb and I tried to drive to Bowen Hills train station for the Bridge to Brisbane fun run, but the GPS took us on the ICB twice, eventually leaving us at a different, yet workable, location. I was not impressed. I think it's time for a replacement.

PS - It's possible that updated maps might fare better.
PPS - And that would be a cheaper option, too.
