I played the prior closed beta.
The game was ass backwards. There is a default speed limiter that is enabled without the player's knowledge, and unless it was disabled it was nearly impossible to complete the opening mission.
As for the driving mechanics, I experienced a bug that made the game unplayable; essentially, my car would move perpetually in one direction (left or right) and at five miles per hour without the ability to change directions or increase speed.
I'm sure the game'll be fine, but I'm kind of pissed the beta was so forgeted up.
