Not really. You have a racing game that sold several million units, meaning several million people who played it. Even if all those players just drove a single virtual mile and never played any further, you'd already be into the realm of "impressive numbers" because at a single mile apiece we're already talking several million miles. If those players average just a few hundred total laps, between however many laps around however many tracks, which might be an average of like thirty-some ten-lap races (track lengths vary, of course, but looking at a typical lap length) or sixty five-lap races, we're now looking at a thousand miles per player, we're now looking at over six billion virtual miles. A thousand miles per player wouldn't be all that impressive either, so one would expect many players to far exceed that, not just in GT5 but in any decent racing game.
When dealing with large volumes, it's easy to find very massive figures very quickly. As of the time of this posting, it's estimated that 387 million newspapers were sold worldwide just today. 4 million cell phones were sold today, as of this moment. $136 million was spend on video games just today. 286 million emails have likely been sent so far today, just today. 23,300 people have died of hunger just today. We've used 300 million MWh of electricity just today. 11.5 billion cigarettes were smoked so far just today.
