ODB2 Bluetooth readers for Smartphones can be had for $10 [1]. I guess the hard part is writing the software that logs all the data. Currently most Android apps simply display the data and don't log it. The logging/software aspect of this is certainly where the value is added.

Not sure if you're interested in such things, but I've written a Python data acquisition framework (and a shitty GUI for my RaspPi) that works with those cheapo $10 dongles that I'll be releasing under the MIT license as soon as I can be bothered. Main reason I haven't released it yet is that the connection management, while quite resilient, is so hackish that I am bit embarrassed by it.

    Nope! Was unaware of the project before you mentioned it. Looks like it might have similar goals.

I've been using Torque[1] for about three years now. It's got a pretty nice UI to show just about anything your car outputs via OBD-II, and lots of things that can be derived from that, as well as integrating GPS and accelerometer data. You can log the data to your phone, as well has have it uploaded to the cloud. The only time I've really used that data was the time some jerk stopped me, cursing at me for driving like a maniac and endangering his children (who he'd been allowing to play in the street). With the logged data, I was able to show that from the time I turned onto his street, I had been going no faster than 10mph below the limit. The OBD-II error-reading software is very useful. It showed me that the Hyundai mechanics were completely incompetent. After holding my car in the shop for a week, they finally concluded that the problem is exactly what these diagnostics told me they were (plus 10 minutes of googling).

  Legal compliance is not equivalent to courteous driving. The other guy may or may not have been a jerk, but there are also plenty of plausible scenarios in which you were also the jerk, even though fully compliant. e.g. rapid acceleration, scary engine rev noise, aiming the vehicle towards the kids as they were moving off the street. Not to say you did any of those things, but I just wanted to point out that being within the law and not-being-a-jerk are somewhat orthogonal .
