I'm not sure it would work. Never mind the politics (someone would be screaming about how much a flashlight, mirror, whistle and garbage bag costs, and how it puts the "outdoors" out of reach for the "poor") and the potential litigation issues, but I have to wonder if it would actually do any good.

In some parts of the world, you MUST have a fire extinguisher in the car. OK, that's all well and good. So are they checked during inspection? (I don't know.) But even more importantly, what percentage of motorists know how to use the silly thing? I truely believe that even you did make basic equipment required, you'd still have the same number of SAR callouts because stupid people will do stupid things.
