I suggest that FD of Brentwood should try lowering his seat cushion. I too am 6-feet 1-inch tall, and drive an automatic. When I bought my present car I experienced a pain in my right leg until I adjusted the seat to its lowest position, and this immediately cured the problem. My wife (who is shorter than myself) drives her car with the seat raised to help see over the bonnet. Whenever I drive her car my leg starts to ache after only a few minutes, but lowering the cushion then takes the pain away. The only downside is that anyone sitting behind me (in both cars) is unable to get their feet underneath the rear of my seat.
