I know OBD2-USB adapters are easy enough to buy (we used one at work to diagnose a hydrogen-conversion Prius), but the comparative ease of using this thing would seriously make me consider buying one. Mostly as a toy to look at sensor readouts, but I'm mechanically oriented enough that, depending on the error, it might save me having to take the car in for work.
"Your son has been in a car crash and help is on the way."
Nice way to freak out parents if it's some fender-bender that doesn't really hurt anyone. I'm hoping it's quite customizable.
I would expect that the crash sensor wouldn't trigger unless the airbag(s) also deployed, in which case it it may not have been a major accident, but it was more than a minor fender-bender. Modern cars (some, anyway) also will refuse to start the engine if the crash sensor is tripped, to avoid a bad condition (if there's no coolant or, worse, something like a fuel leak), so you'll need a tow truck at minimum.
Built for Amercia for those who need alarms in the car for seat belts, opened doors, car keys, lights left on and park brake. You are a bright lot in Amercia.
You know, there are a lot of stupid warning labels here in the US, but my car telling me that the rear door isn't quite closed or that I forgot the keys are in the ignition aren't on the list for me--those are both nice things to prevent minor, stupid mistakes (like my groceries falling out the back of the car when I stop at a light or locking myself out of my car).
I'm old enough to have owned a car that neither automatically turned the headlights off nor had a warning chime if you accidentally left them on, and since there's a dangerous corridor near where I live that's headlight-required, I remember fondly the day when I bought a car that would actually tell me I'd forgotten to turn them off before I killed the battery. Much nicer than that sad silence when you get in and turn the key.
