I've had knee surgery and the "sensitive" part of my knee rests just about on the release button of the brake handle. I did check this out on test drives and decided since this is my daily commuter, trips are short so it's not a huge issue. But if someone makes a decent cover, I'll be checking that out. Thaks for the links.
Edit; had a look and those pads aren't the answer for me; my leg bends at the console so these won't really adddress the issue I have.
