There wave been many roomers that Nascar racing has been like the racing they did in the 70s. Like the "To-the-line", or the last lap pass finishes. How this got started was back at the beginning of the year Budwiser Shoot-out. On the last lap Jamie McMurray had the lead, but on the back stretch Kevin Harvick passed him. Also, back in the spring Michigan race Jimmie Johnson was leading on the last lap but ran out of fuel in turn one and gave the lead to Greg Biffle, but on the back strech Biffle ran out of fuel and gave the lead to Mark Martin and Martin went on to win the race.
Even though those events have happened, It's not like Nascar Racing in the 70s. In the 70s Richard Petty and people like that had the whole Field a lap down and there were only 2-5 cars on the lead lap. Now the cars are so simular to each other that you have 15-25 people on the lead lap at the end of the race.
So even though racing now is a lot like then, there's a lot of differences.
