Same thing happened to me.... Was watching the closing laps, probably about 20 minutes behind real time, and it switched to NBC NY news. DVR doesn't know to follow it from one channel to the next, and I don't count on that scenario to happen so, I didn't have NBCSN set to record, so that's just the way it goes sometimes. As soon as I realized what had happened, I tuned over to NBCSN at that point and caught the victory lane interview.
I still watch (fast forward through with DVR), but it really is a problem with any series of racing, if your ability to be successful in that series is largely determined by either how well you can block/chop others (even if that block directly causes a wreck that elimates many of your competitors....) or success is determined in part by how well you can bump others, again eliminating many of your competitors, without getting caught up in the wreck you actually caused.
In the old days, garage police'n probably took care of things if somebody looked like they took a handful of stupid pills before putting on the helmet... Probably not a whole lot of repeat offenders back then. Driver's/crews found a way to "discourage" repeat performances.
Now, how well you block is admired and lauded by the announcers. Worse yet, when it goes wrong it's rarely the driver's fault according to them.... They blame it on the communication with the spotter... and how tough it is to see... and...and... and...
Last time I checked, there was only one seat in those cars, and only one steering wheel.
