Hi all
Sorry to wake up an old thread but I have one of these boxes in my car. I have to be very careful what I do. 1.9 CDTI Astra, not easy to maintain what they consider a "safe speed".Especially when it doesn't feel like you're driving as fast as you are.
From what I've been told and from what I can gather, the box will pick up on the following:
Speeding: Obvious but will flag you at even 1mph over the limit. I've ben as careful as possible, but take care when "free rolling" downhill
Sharp breaking: some things are impossible to predict when driving, but when the time comes to hit that break, it will flag regardless of whether you are in the wrong or not.
Harsh Accelleration: Even accellerating quickly to 30 mph it will flag.
Harsh turning: not too clear on this one but the guy who installed it told me that it will pick up on turning corners or swerving too harshly
Times that you drive: If you drive between 11pm and 6am you are considered a risk, so this will be flagged also.
I don't think it picks up on whether you have your lights on in the dark, or anything like your door not being closed properly. but don't quote me on that.
Not sure if I have missed anyting out, but they are the main factors. If any of the above is nothing for you to worry about then yes, have it installed, save yourself a few hundred £££'s, build up 1 yr no claims (10 month policy optional) then shop around. otherwise if you have a lead foot and no patience, steer clear.
Hope this info helps
