All phones traveling below 20 mph would be excluded on the assumption that they're not driving. All phones traveling faster than 20 mph would be plotted to discern what road they are traveling on and what the speed limit is for that road.

I just turn off the phone..
- amirmc 13y agoUntil turning your phone off marks you as a 'suspicious person'...
- sigkill 13y agoWith quite a few phones coming with sealed batteries, is it even a reasonable assumption that you've truly turned off the phone?
- mitchty 13y agoSo stick it in a metal box as well. Every escalation can have a counter. If it can't communicate or pick up signal, its as good as off.
- superuser2 13y agoDo dead reckoning with the accelerometer, phone home with your speed later. Or just look at the endpoints of the trip when you take it out of the Faraday bag and calculate average velocity. Or don't try to enforce speed limits through phones, because that doesn't make any sense anyway. Require GPS-enabled governors in all car computers.
