After too many incidents with a-holes pulling out in front of me or cutting me off, I picked up a $15 one on Amazon. The memory card cost as much as the dashcam! Haven't had any problems with it interfering with anything in three years (but then I've an 11 year old truck!). Was really great being able to have my faint of heart wife watch my driving the Going to the Sun Highway in Glacier (she refused to go).
