Oh come on now. I can fit my entire family in a Model S (with luggage) and still do 0-60 on 2.8 seconds. That is, by definition, bleeding edge.
At this point a Porsche is a glorified garage queen.
EDIT: A Porsche 918 MSRP is almost $845K and it's only 0.6 seconds faster than the Model S (P85D). They've made less than 1000 units.
