I've been recording my car journeys for over a year (practically without fail) using my iPhone 5 & isymdvr app (£1.49).
During this time, It has recorded one major accident (video provided to the police), two cyclists knocked off of their bikes and various clips of oblivious road users (one of which which could have been fatal for me..)
Yes it eats the battery (about 30% on a 30 minute commute) but I can charge the phone whilst it records...
The only thing it doesn't do is of course, record behind..
