There is definitely a better way to do so. You can use a magent with a force sensor to detect when the phone is against a metal surface, and only trigger the crash detection if there is sizeable force before the phone detaches from the vehicle. Then Apple would actually be justified in locking this feature to some models, as if normal accelerometers didn't already go to 16G+ :) EDIT: I feel like I may have been unclear. I'm saying the phone should detect if it's being detached from the bike before or after the crash, using a magnetic sensor preferably (since Apple already has their magnetic attachement thing). If the phone is disconnected from the vehicle before it senses a crash, then it's a false positive. If the phone is disconnected at the same time, or less than a certain before sensing a very strong shock, then this is a true positive.
