I thought more than a moment before posting. Whether "estimated life" is MTBF or MTTF: we don't know which PJ is referring to with his imprecise language, nor do we know what hybrid he is referring to either.
But it's irrelevant, really. Unless someone has an accredited source of information where what "estimated life" means is specified clearly and stated to be 100,000 miles, the statement is without truth value. It is intended only to mislead and disparage something that is not understood, for whatever reason. PJ has already indicated that he hasn't a clue about this technology, previously in this same thread, so I suspect it's pure bullshit on his part.
