Re: Cars collect some interesting data...
That's only the data you can easily see - if you have access to the Toyota scantool, you can also see acceleration, speed, g-force and all kinds of sensor data. Some cars even store GPS coordinates of each action, but even whithout that, there is a wealth of other data like altitude, wheel orientation, etc.
Weight of the passenger is what turns the passenger airbag on & off....
Edit: depending on the year, your Corolla might also have a black box that records data just before an accident - it is only accessible by Toyota but it's come up in a number of lawsuits.
