mcracing, I could have not said it better. I too have seen many changes. While I oversee the southern district of our service dept, I still turn wrenches. We have GPS on all our vehicles. There is no one "eyeing the dots" on a regular basis, but spot checks are done. It has been used for discipline and it has been used to protect a tech as well. The honest do not mind, while the others refine themselves or leave. It is a tool for dispatching which saves fuel and time.
