This was a training exercise for aspiring agents who wanted to learn the finer points of tailing a vehicle. The dark car might seem to be the one tailing me, but in fact, the traineees are in a pink Cadillac about 17 cars back, being as unobtrusive as possible. After a suitable period in which I allowed them the luxury of following me, I ditched them with prejudice. They learned their lesson: one never uses a pink Cadillac to tail another vehicle---only an orange Caddy is suitable.
