This is an awesome new development in gaming. It might have been posted before but I only read about it today in the newspaper, so:

Basicly what this technique does is calculating your racing-position in a race with the use of global satelite tracking:

"Alongside you are top names like Lewis Hamilton, Felipe Massa and Kimi Raikkonen. The cars' engines are screaming and everyone is poised to go. For any Formula One fan the chance to race against their heroes would be a dream come true.

Sadly, the closest most of us have ever got is watching the Grand Prix on television. But that could soon change if a company from the Netherlands has its way.

"It's clear that the next trend in gaming is going to be bringing real objects into the virtual world; playing not against other gamers but people doing the real thing," said Andy Lurling, founder of iOpener Media.

The patented system his company is developing sucks in real-time GPS data from racing events and pumps it out to compatible games consoles and PCs.

The idea is that you could pit yourself against the top drivers in the world, as it happens, from the comfort of your living room."

I only wonder... what other uses could be possible after this? 

Deleted post until further notice. Give me some time.

The only problem with this, is what happens when you crash into a real life player, or you take a turn slower than they do, and drive right through you?

I could see this being a really cool feature as a "ghost" race, but to make it as the main part of a game has major limitations, and I'd rather race against other people playing the game online.

I read today that when you drive into another driver, you will get a film of you crashing. if it's a minor crash you can drive on. If you total, you can start over (as racing data is stored)

Yeah, I don't see this as a practical way to play. Collision wouldn't work well.
