A mate is considering buying a P reg C180 classic 1.8 manual which has a foot operated "handbrake" which is another pedal to the left of the clutch.
How do you do a hill start with two feet? :-?
I had a 4.0L Ford Ranger pickup in the U.S some years back and that had the similar system.....apply the 'hand' brake using the foot `till it latches then pull a little release trigger (in/under the dash) when need to move-off....easier than it sounds actually. 
As Debs says, its not that hard, we had a Merc E220 for a week, on the hill come to a stop normall with your left foot brake.
Stop.
Use right foot to apply 'hand' or foot break.
Car holds on hill, when you need to go again, apply power so it takes the weight, and can feel the car pushing against the hand brake.
Right hand side, where the little compartment is on omega's there is a handle, pull it, brake dis-engages.
Off you go 8-)
