So just how long before I can expect this to be the next big POS offered from T-Mobile?

Since they seem to have an issue getting better quality handsets, its inevitable that this Huawei phone will be theirs exclusively. I give it 4 months before it's their next "flagship" phone.

1/32 is approximately 26% smaller than 1mm. How is that even remotely accurate?

Consider, if you want a 3ft shelf and you estimate it using your method you would want a 1153mm shelf when what you really want is one approximately 914mm. That's a pretty big difference. Nevermind how that would scale to anything larger.

Proper measurement of rainfall like that would be acre-ft. So neither gallons or cu-ft would be appropriate.

Seems to me that this program is missing some critical metrics of driving safety. As an app it has the potential to monitor other phone activities while driving. I think that beyond the basic GPS based speed / location measurements and the accelerometer data they should be interested in how distracted the driver is by their mobile.

Say they're texting or browsing the web while driving but still doing the speed limit. The way this program is being described there would be no penalty. In reality the driver is by far more of a hazard to those around them and should pay a higher premium as they are more likely to be involved in an incident.

Linux is supported. They even have Linux versions of MAPLE and other software on the school FTP for the students to download.

I can't comment on their systems because I honestly don't remember. I just recall having access to the software and the availability of support if needed.

The thing is with speeding tickets magnitude matters. There is a graduated scale for the fines with larger fines and more points for exceeding the speed limit by more. So yes it makes sense to challenge the magnitude. If you get a ticket for 12 mph over the limit the fine is say $150 plus 2 points (numbers I'm pulling out of my ass but are fairly representative), now if the automated camera is adding 4 mph more on top that puts you at 16 mph over which would then put you at a $225 fine and 3 points. This is a nontrivial difference.

On a side note, as a designer of roads and bridges I can say that the speed limits are influenced by the geometry of the road and the location (i.e. while it may be geometrically possible it is a bad idea to have a residential street posted for 50 mph). There are some cases where unscrupulous towns/villages/cities will post a lower speed limit than the surrounding areas as a way to increase revenue. This is can be challenged court and is frequently overturned. Also in areas where there are lower posted speed limits for things like curves (black on yellow) and construction areas (black on orange) the lower limits per MUTCD are not enforceable as those signs particularly the black on yellow are just suggestions. To lower the posted limit the signs must be the standard regulatory black letters on white they can only jump 10 mph at a time (i.e. you can't go from a 45 to a 25 in one jump) and there must be advance warning signs "reduced speed ahead". When in doubt about a speed limit or regulatory sign or even a traffic light timing consult a good highway engineering text and the MUTCD.
