I'd agree with you if only the Agera wasn't already gimped by having too much torque and wa-ay not enough grip. If you aren't on an arrow straight stretch of road you can forget about having any advantage at all. The car fishtails like crazy at a very slight input and the output of the torque seems to fluctuate a lot, making it difficult to control with throttle positioning as I would do normally. I'm also pretty sure the gearing is off, since second gear does next to nil and sixth is tall enough to get you within 10MPH of the perf spec speed cap.
The Agera is a gimmick in my opinion. Even when cruising I find no reason to drive it, it's just too much of a pain especially when I can pull the '69 Charger, BNR34 Skyline or even the 370Z and have an easier time of driving in a straight line. If it had a real-steel accurate top speed then at least it would have something to differentiate it from the competition.
