A German friend of mine pointed me at this talk by futurist Lars Thomsen. (Who, if I believe my queries of TMC, would appear to have a P85). Unfortunately, it's all in German, but the short of it (I'm told -- my German is only at a 20% comprehension level) is that he predicts that the tipping point for electrical cars will be in 2017. His claim is that by then, electric cars will be both less expensive and better than equivalent ICE vehicles. If nothing else, the comments under the video are worth a browse.
