A few weeks ago, I went to DMV office in California to renew my driver license. They asked me to take an 18-question renewal test. I took the test and passed it and received my renewed driver license, assuming it's a normal procedure for everyone.
Subsequently, I learned that not even one of my colleagues or friends were asked to take this test. In all my life, I've only had two parking tickets. Is that the reason that I was asked to take the test?
