I took a few minutes to look back at one of the previous start time announcements from the fall of 2009, talking about the standardized start times for the 2010 season and beyond. It's kind of funny to read what was said back then about the importance of the standardized times vs. the most recent announcement from yesterday. Here's a link to what I'm referring to. It's a transcript of the announcement. Long but interesting to read how what was once so important doesn't mean squat now.

SiriusXM NASCAR Radio hosts will push this topic all day stating the good in it. Kind of funny as some of these same hosts were talking just six years ago how important the standardized times were. Flavor of the month I guess.
Personally I like the later times. It works better for my schedule to be able to get things done and then sit down later in the afternoon to watch a race. It doesn't really bother me as an attending fan because I always take extra days after the event in the case of weather and the like. Most times I camp at the track anyhow so the race time is a non issue.
