Must be some sort of mistake if it says 2011 somewhere. I think those 12 Roadsters got to Japan in Mid 2010.
Also, maybe the log you are looking at is not from the beginning. Maybe someone "wiped" the memory when the car was first sold or something like that.
I expect some LogParser experts will chime into this thread soon and answer your other questions.

There is an interesting 0 in the CAC column row on the date the battery was said to have been changed but the CAC the line before and after that zero are the same which seems odd if the battery was really changed out. I would think the new battery would have a higher CAC than the old one...
Those two photos of Roadsters look a lot like it. No way to know for sure.
