The parallel acces road glitch is a classic one, once I drove well over a km before it figured out I left the highway, and the distance between lane 1 of the highway and the acces road was more then 15 meters when it finally re-routed.

As I said, our different perception might come from the differences between the street network in US and Europe cities. When you have two lefts separated by 5-10 meters any civilian Gps I used has a problem if the software doesn't instruct it to tell you "take the second left".

Or maybe uncle Sam allows better GPS readings for the civilian use on US soil (but this kinda makes no sense)
Like the recreational trail example I gave before, it probably has a lot more to do with how the map data is uploaded into the system than the GPS itself. This is not the fault of the GPS device or the company. I'm not sure which government agency is responsible for this, but it's sure seams like each county in the US submits their own data.

I found myself approaching an 8-lane roundabout somewhere in SoCal a few years ago. The GPS gave me pin-point directions for the "exit" I was supposed to take.

Shame the naut. GPS' are so pricey...I guess supply & demand.
I'm thinking of what $900 could buy for my Shark (I was straying too far off topic)
They start at around $400 + maps.
They can also be used in the car by purchasing road maps.

(both the current GPS, which is US military stuff, and it's russian counterpart are accurate and ofer real-time positioning only when used with proper military equipment, we will have to wait until 2013 in order to get civilian stuff that actually works http://en.wikipedia.org/wiki/Galileo_positioning_system ).

I was not talking about car GPS. I was talking about chart plotters wit WAAS enabled. This is much more accurate. Kinda important when you are on a boat.

I used to really dislike roundabouts, now that I have the GPS, I still really dislike roundabouts.
