The first 189 laps of the 1992 Indianapolis 500 was a bitter-cold crashfest dominated by Michael Andretti. Andretti led 160 laps and had 22 of the fastest 25 laps of the race. Only one car manged to pass him (Al Unser Sr) under racing conditions. But on lap 190 his car came to a halt, passing the lead to Al Unser Jr. under the ensuing yellow flag to tow in Andretti's car. Racing resumed with seven laps to go and Scott Goodyear hot on the heels of Unser. Lap after lap they ran nose-to-tail with Unser appearing to be faster in turns 1 and 2 and Goodyear able to close in turns 3 and 4. Coming off the final turn of the race, Goodyear closed in enough to make a pass attempt, but it wasn't quite enough as Unser beat him to the line as Unser got the victory in the closest finish in Indy history.
