Don't you think that the vast majority of dangerous human drivers would be perfectly capable of changing their behavior during a driving test? Even without any malicious intent most people would be more careful during a test.

No, I don't actually. Can't turn off stupid.

I want a camera on every traffic light and stop light - or better, cameras on a random 20% subset of intersections. The system would automatically flag infractions for human review. Combined with docking points off people's licenses and/or fines based on income/wealth percentage, this would be a decent deterrent.
