Dan:
I'll let the experts weigh in on the pedal pressure end of the problem but for hitting more than one pedal at a time, get a pair of driving shoes for your outings in the snake. I've been wearing Puma Speed Cats for years and they work well for me. The problem with most casual athletic shoes today is that they're made for people who want a very wide supporting platform for the sole of the foot. Not needed for driving.
I've had any number of people sit in the car and remark on how close together the pedals are.
