Above you see some telemetry data from my car during my trip home from work. I recorded it using V-Cockpit GPS 2.0 for iPhone 3GS, but is it useful? Well this data is not really interesting because nothing happened. Just the normal traffic jam :)

However you can imagine in a few years that all cars are fitted with sensor logs like this to analyse an accident? Or perhaps…by lease companies to see what is happening to their cars? Of course you can also add positioning data (GPS) to see exactly where what happened. Anyway, it’s up to your imagination.
