The "renew my car registration" example was intended to imply that'd I've chosen to "give them some connected dots" - dots which are operationally useless (or worse - preferably adding noise to make the job harder and evidence that the job is sometimes wasted effort).
I'm assuming "they" have access to government servers and networks, and that they'll easily be able to connect me - as a real and (at least mostly) law abiding citizen - to a clean-slate browser using SSL over TOR - logging in to a government web server with real world credentials and doing some mundane and law abiding everyday task.
I don't get what you mean. You think that once you connect to https://site.gov/ they can easily match the traffic entering the tor network with the traffic that exited tor and initiated the web connection?
