Exactly the point!! if you're zig zaggin that much you definately need to have the cops get called! But on a serious note, how could it be 50 meters? That's about 165 feet... in certain cases about 3 different roads... Most of the Garmin products are at 1m/3feet resolution. I'm sure that most consumer devices are within about 2m/6ft. Do you have numbers that I don't in this case? Bryce Leo I'd have to agree on this one, I use GPS systems in several areas and generally see resolutions between 2 and 10 meters on average with 5-6 sats in use. Granted to detect zig zags you'd need to be quite careful with how you used the data, telling the difference between weaving and dodging pot holes... Maybe I should light the touch paper and suggest this be a use for the famous accelerometer that's been mentioned so much ;-)
Yes, the accelerometer :) . And, now that we are at it, why we just don't add: pressure sensor (atmosferic), temperature sensor, relative humidity.... It would just be under US$50 all of these.... well, plus about 2-3 hours programmer time (more or less, depending on the skill), and about 2 hours of the electronic engenieer (to implant the thing into the device's design).
