Great post.....This was my exact thought when I saw the picture that Steve posted on his last tweet. I also stated in response that it looked like something that would be used in an assembly line on automobiles.....
I think that we are on the verge of very big developments....
It's hard to tell given the angles of the pictures and the positioning of the CM ruler. The first picture appears to be longer in length than the second picture. bSafe OBD-II unit has an inside length of 1.75" but there is usually some space around the inside perimeter of the unit to fit the circuit board into. Let's call it 1.625" (1 5/8"). That would translate to 4.1275 cm.
641.jpg is about that length, however 640.jpg is definitely smaller.
It looks impossible to teardown the bSafemobile unit I have without destroying it first, but it may come to that.
