We have all experienced strange routes that our GPS sends us down.
Once a rider was directed to a dirt road over a mountain since it was a couple of miles longer to take the beautiful paved road around the mountain. A recent driver drove up a highway exit ramp beginning to enter the high-speed highway in the wrong direction when, fortunately, only a minor collision occurred.
Can the driver be relieved of liability by claiming she was following GPS? NO! All drivers have an obligation to drive in a reasonable and prudent fashion. They are obligated to follow the reasonable speed limits, and highway signs including "do not enter" signs that are located on every highway exit. Just because the person on the GPS monitor instructs you to take a left now does not mean that a driver could or should follow any directions blindly.
