I looked into getting one of those once, figuring I’m a safe driver and therefore would only benefit from it.
What I found on the Internet were (self selected, admittedly) stories of the presence of the device making your driving less safe. Since it’s basically an accelerometer, sometimes it’s “safer” to take a curve fast than to brake for it. Or fly through a yellow rather than stop at it.
I have no doubt there’s correlation between those devices’ scores and accident proclivity; but I’m confident my driving is safe as-is and would rather let premiums go down after accident-free miles than on the say-so of a nanny device.
So I bought a dashcam instead, hopefully to avoid being ruled 50/50 at fault if someone hits me.
