The problem is that racing games are long-legged. Games like Mario Kart and Gran Turismo sell for long periods of time. Thus, any game released after them has to compete with them. It's a risk to release racing games, as they'll be pitched up against some seriously strong series.
I checked the top 100 for 2012. Somehow, Mario Kart DS is there, despite having had 2 sequels launch for it, and being in its 8th year. It has a shot at selling a million this year. Games like those are a nightmare to be pitched against, because even 7 bloody years after it released, it's still a competitor for your sales.
