A modified "Cash for Clunkers" revival sounds pretty smart. My family's driving has plummeted, and now we have an extra car which we never drive. Meanwhile there's (I presume?) increased interest in the car-based gig economy. If someone were to want my 18 year old rust bucket (runs great!), I'd off it for cheap, since the insurance, registration, and its physical form are all deadweight. Then I'd buy a new car once the economy begins to recover. Why not make this dynamic part of the automaker bailout?
