We don't have mushy peas in Australia, but I lived in London for 3 years, so I remember the strange mushy peas. I think I tried them ... once?? It's probably one of those things you have to grow up with to love.
Oh, I think there's 'eel liquor' in them, maybe? Cos my dad has a life-threatening fish allergy, and I think I remember him having a bad reaction to mushy peas.
