I fail to see how recording driving patterns is going to stop people from crashing into things like Farmer’s Markets.
According to Joe Osterman, director of highway safety at the NTSB, the recommendation was inspired in part by a tragic auto accident involving a 86-year-old man who drove his car into a crowded Santa Monica farmers’ market last summer, killing 10 and injuring 63.
Osterman said a black box in the car might have not saved the people in the crash, but would have allowed investigators to find out how it happened and how cars could be better designed to reduce the likelihood of greater injury in the future.
Not So Fast 
“…would have allowed investigators to find out how it happened and how cars could be better designed to reduce the likelihood of greater injury in the future.”
They can design cars to guard against 86 year old drivers? Sweet.
