Peart was a fan of Ayn Rand. "Red Barchetta" is a paean to personal freedom and property in the face of (leftist) government control which one could still imagine coming true in the not-so-distant future if Democrats get complete control.
Yes, I heard “Red Barchetta” is based on a real book. It has a futuristic sci-fi theme to it. In it, the “motor law” made internal combustion engines illegal, and the protagonist is a rebel who secretly drives an old car along country roads and almost gets caught.
