The thing is, I am an engineer. Well not a licensed PE, but my job is engineering. I understand these issues, have contacts in the automotive industry which I speak to and learn about the issues as seen from the inside.

I was emailing, not to change his mind, but to see if there was justification for some of the "facts" in the report that I take issue with. Such as the disproportionally low hybrid useful life span. Or very low operating miles. These are both HUGE problems that cause the "data" to be off by probably several orders of magnitude.

His childishness was illustrated well by his attacking my literacy without knowing anything about me. I can only presume it is his way of shielding himself from any real criticism.

Bottom line, if they attack data collection with the same professional nature they attacked me, then it is not surprising that the report reads like a report written to make a big 3 automaker executive confident he is making the correct decision to de-fund R&D in the hybrid segment.

People must buy these reports to reassure themselves they are making the right decisions.
