Yes, it's exactly like that scene in The US Office.
A motorist in Ontario, Canada, was following GPS instructions on a particularly foggy night when, she took a wrong turn - or a right turn, depending on her SatNav - and ended up driving down a boat launch in Lake Huron.
The woman, thankfully, was able to escape with her handbag and swam to shore. Her Toyota Yaris, however, sank to the bottom of the lake and had to be fished out the next day. The unnamed 23-year old woman managed to get help from a nearby hotel.
Local police admitted that the boat launch where she drove off can be deceptive, especially in foggy weather like the night in question. As for the woman, she's admitted to being more than a little embarrassed by the whole situation.
