Re: Not a bad idea
I'd be careful of what you wish for. We're already having our privacy eroded on the Net by governments, corporates, etc.
This is a very slippery slope to be on. Ok.. so they use it to enforce speed limits. Then what? Visiting certain neighborhoods? Attending meetings... especially political? This will escalate so fast in almost every country I can think of that it's scary where we could all be in a few years.
Go read the posts and articles on "snooping",... this is just as bad, maybe even worse.
