Driving is arcade, but fun arcade. Tracks are extremely arcade, but so far I'm enjoying them.
The thing that astonished me is that it lists the World Leaders, Country Leaders and State Leaders (for USA), and people have obviously taken this very seriously. My first race I did kind of okay and was in the top 10 percent among World Leaders (out of over 300k players), but that was an anomaly. I didn't get back in the top 10 percent on any other track that I played.
I'm not concentrating on the leaderboard yet, though. I'm just working my way through the tracks and having a great time with it. At some point today I might try making my own track.
