No one's due process rights are violated by this. However, it does strip people of their anonymity while operating deadly machinery, but there is no right to drive; it is a regulated privilege, thus such an intrusion should be Constitutionally permissible.
Let's face it, our current way of doing things involves an assumption that people are basically civilized and somewhat responsible citizens. Clearly there are far too many folks who don't measure up. I'm sick of giving them a pass, especially when that pass is written in the blood of cyclists, pedestrians and other innocent victims (even other motorists).
The alternative is that more and more of these crimes will be solved with the use of surveillance equipment. This will lead to even more public support for our trend towards a total surveillance state, since (almost) everyone likes it when an evil person who tries to get away with murder gets caught.
