I'm sorry, but then I don't understand the point of the original comment. As we agree, you can already buy a lightweight two-seater track car with very good performance for quite cheap. I understood the point of your original comment to be that with active aero devices we could now have something far more practical, like a Nissan Leaf, but still having very good track performance. If that was not the point, then what is the new thing you think is going to be enabled by active aero?
