Happened again last weekend on the ride to Ashley, 3 riders (me) turned right following the map as the "pack" just kept going north. Yelled out..."Right turn!" to no avail. We three then had to hammer to catch up to the pack.
Jeff, a couple things happened in Auburn on that ride. The lead riders were not reading the map. As I recall the road we were supposed to turn on north of Auburn is shown on the map as CR40 while I believe the street sign says Morningstar.
While the turn may have been missed I think the correct approach was taken:
1) When riding follow the group, do not make a turn that the lead riders did not signal and make. The danger that exist is riders beside or behind you may follow the lead riders while you are turning. This creates a potential for overlapped wheels and a crash.
2) The road we were riding on was a bit busy and trying to get all the riders to make a U-Turn just to get back to a misssed turn would have been more dangerous than simply proceeding forward.
3) Continuing straight was going to reconnect us with the route and allow us to head on north to Ashley.
4) While the Garmin's may be useful tools for some they are not foolproof and should not overide safe decisions or personal knowledge of roads that the computer directs you to follow.
With regards to the insurance, it is designed as a supplement and not a replacement for carrying appropriate primary care insurance. While nice to have I am not going to make unsafe moves simply to adhere to some map to qualify for supplemental insurance.
