I have just been playing Gran Turismo 5 and unlike many other people I actually like the game, the addition of the top gear track, the mass array of cars and tracks and the game play style i find extremely fun.....but and this is a big but, i think racing games today should all have the rewind function. I loved it in Forza 3 and Dirt 2 and it came in very useful at times. By all means limit it to so many per race so I don't spam the button but atleast have it. Like I said just playing GT5 racing in an extremely long race and I am on the last corner. 20 minutes of game time in this one race alone. I am in 1st happily racing along. Oh no my head itches......do I scratch it yeah i need to its annoying the fuck out of me. But as soon as I scratch that bloody itch I am off. Last corner 3 people pass me no chance of getting back in it. So I turn the game off in frustration. If I had a rewind function I could have easily rewound that mistake and won my race and still now be happily playing GT5. Instead I am on here ranting to you.  
 
What do you think should all racing games add a rewind function or is it just a pussy whimp out move?

I'm the opposite: I like games that can go wrong in an instant. I'm not a big racing fan, but for instance in IL2: Sturmovik (for PC, not console), I can do my pre-flight, take off, pull into formation and remain in formation for an hour or longer (real-time), only to have the screen suddenly go black because a lucky flak burst penetrated the cockpit, or a stray bullet from a dogfight found my pilots face. Poof...over. No redo, just restart the mission.
 
I find it adds that white-knuckle "this shit can get serious any fucking second" sweaty-palms anxiety that while I'm sure pales in comparison to the real thing, is the closest I'm going to get to flying a hunk of metal over Russia/The Pacific trying to win a world war.
 
I hope.
