It's not unusual for your GPS to get you lost. Whether it's outdated maps, or a diversion due to road works, that throws you and your gadget off course, it sometimes takes a while to realize you're going the wrong way.
A few months back, we heard about a woman suing Google for giving her bad directions and directing her down a rural highway. The woman was subsequently hit by a car while walking down the middle of the busy road and blamed Google for her being there in the first place. While that was clearly a case of someone blindly following instructions and not employing common sense, a recent case in Spain is less clear-cut.
Last weekend a man in La Serena died after GPS directions led him into a lake. Gizmodo cites a Spanish newspaper report that says the man and his friend were led down a rural road that ended abruptly. It was dark, visibility was poor and the man, a foreigner not used to the area, didn't see the end of the road until it was too late. His car dropped into the lake and sank in a matter of minutes. While both men were able to get out of the car, only one was able to swim to shore.
It's not clear whether there were signposts or a blockade to warn drivers about the lake, which makes it hard to know who or what is to blame. Though one could argue that this is just another case of humans relying too much on their gadgetry and not enough on simple common sense, visibility was clearly quite bad at the time of the accident so it's hard to fault the driver. However, El Mundo also reports that the GPS did say the road ended in a lake but the men just didn't stop on time. Unfortunately, the situation probably would have culminated in the same tragic accident had his friend directed him down the road.

Or as smart as the people using them are, but sometimes accidents happen too.
It is the responsibility of the driver to adjust his driving to the environment. If he cannot stop in time to avoid a stationary object, then he was clearly at fault - whether he was driving too fast or was somehow distracted.
Sure, he may have had no reason to assume there was a lake in front of him. Every time I drive, I keep in mind that there may be a vehicle, person, animal, road damage, a snow drift, fallen trees/rocks or some other object in my lane. When it rains or snows, I drive as if the road is slippery. When it's dark, foggy or snowing/raining hard enough to effect visibility, I drive only as fast as I can see.
Regardless of whether the GPS is found to be liable, above all else, it is the responsibility of the driver to drive safely.
@Jane: I tend to like your articles, but I pray that you don't have a driver's license.
agreed. plus the gps company would win since they a clause which states that they aren't accountable for any errors with the unit and that the unit may not be accurate all the time
