Repeat Offenders

course to be taken, for insurance relief, a
limited amount of times. Why not get as
much as you can out of them as possible?

How Feasible Is It?
 All of the hardware needed is currently
available via COTS (Commercial Off-theShelf) components
 The software component will have to be
designed and implemented
 Laws will have to be changed
CS410 Green Team

Feasibility Problems
 Having product accepted as a mandatory
driving instruction component
 Largest problem currently
 The hardware components will have to be
married together in a specific way
 Very technical and complex
 Software will be complex
 Will take a while to get right

States have different interpretations of
 Who owns information collected by black
boxes
 When a court order is required to collect black
box data
 Whether drivers need to be informed if the
vehicle they are buying has a black box
