I have been in 2 accidents since December 27th; neither one gave my family the notification. One I was going 40 mph the other 75 mph. The air bags deployed and all. The car was totaled. This "crash detection" DOES NOT WORK. I pay extra for it because I have two teenage drivers. What a joke. I'm waiting for a line 360 to contact me. I have emailed them!! Also, half the time, it is not correct. It will say someone has arrived at school, home, work, etc. 10 minutes late. If even at all.
