For production cars, absolutely.
Do you think great cars of today from Ferrari, Lamborghini, Aston Martin, GTR all had inputs from race car drivers? These cars are all design using computers and wind tunnels.
In fact, without Senna, Honda was able to extract so much more from the NSX with the NA2 Type R simply by using the wind tunnel, something they didn't get to use back in the 80's.
no car is designed on a computer, then sold as is. they have in house drivers putting countless hours into developement. Senna gave a small contribution to the car that Honda engineers and drivers did not catch, which was it needed more stiffness. I am sure they all find racing drivers for feedback, but it is not always publicized. Ferrari's do get input from their F1 drivers, but most of the work is done by unsung heroes.
anyways, regardless of which racing driver provides input, no car will be tuned according to their preferences. it must be driveable by all, not just by the best drivers in the world.
