It also looks like a patent on elements of networked fleet vehicle tracking, which has been around since the '90s.

If I've learned anything about the patent system, it's that it doesn't matter if you've been doing it since 1776- if they've got a patent on it, you better watch out.

If you personally have been doing it since 1776, you're fine. It's usually more like some obscure product by a now bankrupt company did the same thing, but neither they nor the product is currently available.
