> What happens if the thing thinks the speed limit on a 65 MPH highway is 30 MPH?

A couple thoughts on that.

1. I would expect that they won't be developing their own system for finding out speed limits and monitoring for changes. They will most likely use the same commercial sources that are used by many mapping and navigation apps and built-in car navigation systems.

Those sources do occasionally have errors, but the only roads with speed limits above 55 mph there are interstates and some major divided highways. Those are all high traffic roads with plenty of drivers using navigation apps on them, so a speed limit being too low in the data is going to get quickly noticed by a lot of people and reported.

Less frequently traveled roads might have data errors that last longer, which would be annoying, but the limiter does let you go 10 mph over what it thinks is the posted limit. I expect that the most common error will be missing when the type of zone changes. For example you have a 40 mph road and the data mistakenly says it goes through a business zone when actually it goes around that business zone. Business zones typically have a 25 mph limit, so you'd be stuck going 35 mph (25 mph it thinks is the limit plus 10 mph) instead of 40 mph until you get past what it thinks is the business zone.

That's annoying but it is not so slow compared to the real limit that you'll be a danger to other drivers.

2. Route around the error if it is too annoying.

Virginia law only gives judges the authority to require someone to use this if they have been convicted of speeding over 100 mph.

That's 30 mph faster than the highest speed limit in Virginia, which is 70 mph on interstates and a few major divided highways. The limit everywhere else is 55 mph or less.

20 mph or more above the posted limit or over 85 mph in Virginia is reckless driving which is a criminal offense (a class 1 misdemeanor, which is the highest level of misdemeanor) rather than a mere infraction, with up to a year in jail and/or a $2500 fine.

There should only be a few people who are forced to get one of these limiters, and they are people who arguably should be getting their driving privileges suspended for a few months at least.

If they are given one of these limiters instead of their license being suspended and so driving will be inconvenient for a few months, I'm having trouble dredging up much sympathy for them. It's kind of like when someone in prison is paroled two years before their sentence is up, and then complains about the burden of having to check in with their parole officer periodically for the next two years.

My feelings on people with that kind of problem are nicely summed up by Frasier's response on an episode of "Frasier" when a caller named Roger on his radio show wanted advice on something completely stupid:

> Roger, at Cornell University they have an incredible piece of scientific equipment known as the tunneling electron microscope. Now, this microscope is so powerful that by firing electrons you can actually see images of the atom, the infinitesimally minute building block of our universe. Roger, if I were using that microscope right now... I still wouldn't be able to locate my interest in your problem. Thank you for your call.
