It's terrible. I'm watching the trailer/gameplay and it is totally nothing to do with Ridge Racer. Like a previous poster said, it's more similar to NFS or Burnout style.
Ridge Racer visuals are stylish, colorful, and have awesome environments. This seems more gritty and has an "underground feel". Even the soundtrack doesn't feel the same, I miss the soulful beats that the RR series is known for.
This whole game feels like an "American-spin" on the franchise.
I'll give the demo a try before I make my final judgement, though.
The fact that it is not Ridge Racer (which it's not). The problem is that it is too hard. Pure, Split/Second, and Blur all failed commercially at least in part for this reason. Don't get me wrong, I like those games. But there has to be some compromise between hardcore fans and more casual fans, do that the more casual fans don't get shut out of the game. The difficulty level here is brutal. Just brutal. This type of game will gain a cult following, but it will never flourish. --- "Well, it's not going to run at 2GHz because the battery would last five minutes and it would probably set fire to your pants."
