Here in S. Fl, we get the errant car in the canal story all the time, at least once or twice a month, some make it, some don't. Panic sets in, and most folks get disoriented, and drown.
Tragically, there was a mother of two, texting while driving in the rain, ran off the road, overcorrected, and slid sideways rolled over into a shallow canal.
Witnesses jumped in and managed to free the driver but her two children drowned, all in less than 3 minutes.
