John Smith absolutely could end of on the list. There was a T. Kennedy on one of the many, many lists, and Senator Kennedy was affected for several months before his friend Tom Ridge (Director of Homeland Security) straightened it out.
Let's not forge that the plates do not in fact identify the driver. They identify the car - and through a search of government records, the owner. Upon close inspection, they also identify whether someone has paid the registration (i.e. usage fee).
In IT terms that might be analogous to the MAC address on the network card in the computer or other device.
There is a big difference between voluntarily giving Google or Facebook data, and the government (any government) just taking it. If you don't like Google, there are lots of alternatives. If you don't like Facebook, don't use it.
I disagree with the sentiment of this post. Your college degree only gets you the first entry-level job. After that, it is your performance that matters.
You don't get to 'practice your surgical skills' until you have a done a pretty extensive internship, which includes a lot of supervised hands-on work. Same with building a bridge or a dam.
While I don't condone cheating, I also don't think that your school performance means anything once you are past that entry-level job. I do a lot on mid- and senior-level hiring and your college performance (and even degree) means almost nothing to me.
Diplomas may be relevant in many fields because they kind-of set a baseline of what is expected to 'know' in order to do the job.
That said, I had a colleague (in the IT field) who insisted that we call him by his Professor title. Which I did, until I found out that his PhD was in Zoology. Which is as relevant in the IT industry as my own Hotel & Restaurant Administration degree.
