[time-nuts] Problems with Garmin - maybe we should cut themalittle slack

I thinks that's because the algorithms used work well most of the time, simply not all of the time. You can call it sloppy work if you want, or you can call it an example of effective business model: provide a tool that will satisfy 95% of a perceived (or real) need for the price of an average Christmas present. It is called value pricing and has nothing to do with development costs.

In my neighborhood, the Navteq map assumes that there are 100 houses in each street. There are actually about 50 houses in each street (there are about 5 or 6 streets the same length), so as I live at number 47, the Navteq map puts me in the middle of the street instead of being the last house on that street.

It sounds ridiculous, but if someone was not able to find my house while using a GPS with these maps, I would question the person rather than the GPS. 

The situation would be considerably better if all streets and houses had clearly visible names and numbers, but that's another issue.

 alittle slack

I add just one more comment ...

Most of the destinations I program in, by address, work well.
Most of the time, I get led right to the door. So why can't 
it figure out where I live ??

Just sloppy work, pure and simple.
