Well it does look like a pretty wimpy car tire but ever since I heard about dark side I've been thinking it has to be an awfully small tire to fit most bikes. I would think any fire that small would be designed to fit tiny, low performance economy cars. That is what we seem to be looking at in this photo.
Ok, but, again, to rehash the whole pro-con argument, assuming these pics are a fair enough representation, MC tires are designed to lean and to fit to a MC rim, and, especially, the bead. Car tires are not. Even the pro dark side vids showing car tires on bikes, a camera from underneath showing the contact patch, show this huge distinction.
Car tires would make perfect sense if you never lean because they have far more contact patch than a MC when going straight.
Past that, any grip a car tire is designed to give is in context of having 3 more helping out so, harder compounds with less grip make sense because there is help, a balance between OK grip and longer lasting.
For a bike, frankly, wear says "GRIP". A tire wearing is the result of friction and, on one extreme would be a really sticky tire that doesn't last long at all and the other would be one that lasts a long time at the expense of grip. So, somewhere in between is the ideal and the ideal is going to be based on bike and riding style.
You go into a corner pretty hot and think of the enormous pressure on that tiny contact patch, the ONLY thing keeping the bike from sliding out. I'll take more grip. That's why I kept going with the Exedra's so long; I had zero complaints about the grip.
