Hi.
A funny thing happened to me when I shifted from M/T (RAV-4) to A/T (Forester) - my right leg started hurting!
I think it's got something to do with seating position because each car has different ergonomics, so to speak. Even the pedals (accelerator and brake) have an effect I think.
I started adjusting the height of the seat, as well as the recline but the pain persisted. So I adjusted the seat so I'm closer to the steering wheel and my upper leg (almost to the knee) is supported by the seat. The pain is starting to fade, thank goodness.
