midnight
The DHS had put FasTrak readers all over town -- when you drove past them , they logged the time and your ID number , building an ever-more perfect picture of who went where , when , in a database that was augmented by `` speeding cameras , '' `` red light cameras '' and all the other license-plate cameras that had popped up like mushrooms . No one had given it much thought . And now that people were paying attention , we were all starting to notice little things , like the fact that the FasTrak does n't have an off-switch . So if you drove a car , you were just as likely to be pulled over by an SFPD cruiser that wanted to know why you were taking so many trips to the Home Depot lately , and what was that midnight drive up to Sonoma last week about ? The little demonstrations around town on the weekend were growing . Fifty thousand people marched down Market Street after a week of this monitoring . I could n't care less .
