I haven't really watched IndyCar since the early 90's leading up to the reign of the Ganassi team in CART. The split with the IRL killed all interest in it for me.
I watched most of today's race simply because I'm a Rubens Barrichello and F1 fan. The new cars look good, and it's certainly nice to see Chevy back in it, but overall I thought it was pretty boring. I don't mind spec tires at all, but a series with a spec chassis does nothing for me. I guess modern IndyCar racing just isn't technically interesting to me now.
Unfortunately, it looks like exactly what it's supposed to be: 'cost effective' racing. But I guess that's the reality of modern-day racing. Shame.
