I have the slightly longer car but I still cannot stretch my left leg, I have to drive with it bent to clear the clutch. I have lifted the front of the seat a bit & that helps. Over a 2 hour drive I dont get numbness but I use an Airhawk inflatable cushion that I had for my scooter. There are various sizes & shapes for bikes trucks & planes. There is a budget version but its unrepairable if punctured. You need to experiment a bit to find the right inflation. The cushion raises me bit which I like for visibility. I think I'll ask about moving pedals to right & forward.
