Aw, c'mon guys, they're not that bad!
Seriously, Bill made the most accurate diagnosis with his post (the second post on this thread) - have a look at the routing preferences. If you're not sure, reset them to default. On the SP 26xx series, you can find an option to reset just about any set of preferences to default (without messing up other preferences) by pressing the MENU button a second time when you are on a specific setup page.
The other possibility is there might be a slight error in the cartographic data. I don't mean a visible error, like a road missing, but an attribute error, where the person who was digitizing the map finished work one day at 5:00 PM, went home, came back to work the next morning, started back on a continuation of the same road, but forgot to join the two together.
There are a few of those around - one infamous one is on the 401 expressway in Canada (Canada's most travelled road) - where the GPSR will ask you to get off at an interchange, go 200 yards down the road, make a U-turn, and get back on the same expressway again. Visually, you can't see a break, but there is an "attribute" break in the roadway. It's embarrassing, but NavTech usually gets a lot of feedback about these goofs (they are NavTech problems, not Garmin problems) and they never last for more than one version of the product.
Hey - if it doesn't look like it makes sense, don't follow it. Whenever I am in a totally unfamiliar area, and relying entirely on my motorcycle GPS (or aircraft FMS) for navigation guidance, I always zoom out to a pretty big scale every now and then, just to check for "reasonable-ness". The electronics are very powerful, but they have no critical reasoning - we have to supply that.
