I've recently become vaguely fascinated by racing, but I don't know how to start following it since where I live the only type people follow is NASCAR (which I know has strategy and technology behind it, but I find it tedious. Personal taste.). I'm more interested in what I think may be referred to as GT racing, with the more experimental and purpose built cars. I'm fascinated by the less restricted engineering competition between companies and racing prototypes. Can someone tell me what I should look into or something? Or give me an overview yourself?
