The Victorian police system was first running in cars on public roads in 2012. No doubt there are plenty of solutions available today that have been developed since then, but they probably weren't considered at the time. That $86m has covered development of the software and hardware and at least six years of running costs for the program. So yea, I'm sure $86m sounds like a lot when you compare it to some random piece of software that does a small portion of the project.
