Formula 1: Boy, they blew that redesign. The aero kit is ridiculous, and the bigger tires hurt more than they help. Lap times were no faster at Melbourne than they were last year, and an overtaking car could get no closer to the car he was catching than to be trailing by 1.5 seconds before the dirty air from the leading car stalled him out. Not only was there no passing, there was never any hint that there might be passing. They have a lot of work to do to make that sport watchable.
NASCAR: Still doing the boring parade for 380 laps and then ending the race with an "exciting" 20-lap wreckfest, justified by the triteness of "cautions breed cautions." Actually, idiotic driving is what breeds cautions, but the announcers will never admit that a NASCAR driver exhibits anything less than godlike perfection. Admittedly, once in a while a caution is due to a blown tire.
The new "stage racing" means that they no longer have to throw "debris cautions" to try to keep Danica Patrick on the lead lap. Didn't work, though; she finished 26th, two laps down.
