This will be an interesting dialogue. I'd like to see what all the fields are in the db, and it would be interesting to try to see if there is any way to access the data.

I might even like having such a thing in my car, in order to prove my version of events, when I know I was in the right but don't have a witness handy to back me up.

The other side of the coin, of course is: Do I have a right to expect that this information is private? or that I can delete the information if it would prove that I broke the law?

Say, for example, the system keeps a data point for the highest speed ever logged, and the date and time. If there was no cop to catch me and give me a ticket, that would certainly be evidence for one to be issued. While I certainly wouldn't like that, is there a right for me to get away with something merely because I didn't get caught?

If your hypothetical includes GPS technology and records the location as well (think OnStar), your goose is cooked. ;O)

Recording the highest speed you've driven could only be cause for a ticket if it was hooked to GPS data, without that there's no way to prove you were on a public road and the speed was illegal.

Nonsense. Ever hear of private property? Or Montana?

The reason we have public safety laws (supposedly) is to deter behavior that creates a risk to public safety. If you drove fast (perhaps even in violation of one of those venerable signs) and hurt no one, then public safety does not require your being punished. German autobahns are as safe per vehicle mile as our Interstate highway system, tied for the two safest road systems on the planet.

Don't believe all the nanny-state claptrap you hear about speed limits.
