The difficulty balancing across Driving Challenge is decent, with the bronze medal usually attainable, but you can also skip tasks if you struggle.
You could argue that you're getting all the content you could possibly want and are then invited to explore it without restriction, and it's certainly possible to enjoy the game like this. I've lost countless hours over the weekend hunting down slippery sports cars, turning off all the assists and fiddling with Quick Tune, and then pitching them against hectic circuits in Drift Trial, my particular favourite.
But structured single-player career modes are more than just fuss; they're a way to regulate difficulty, excitement and choice so that the player gets just enough of each on an ongoing basis. Relying on players to make their own fun is either lazy or foolhardy. Coupled with archaic AI and the isolating absence of PlayStation Network support, this makes for a game that feels unfocused and regressive, despite its considerable technical and mechanical accomplishments.
