IndyCar's re-introduction of a universal aerokit in 2018 saw the aesthetic appeal of the series take a monumental leap forward, and also brought an end to the days of countless meaningless passes in the Indianapolis 500.
All the 500s staged in the DW12 era - between 2012 and 2014 with its standard aerokit, and 2015-2017 with the ugly manufacturer kits - were entertaining, without question. But the cars ran in packs, and the passes looked too easy: the guy in front - providing he didn't throw a vicious block - pretty much had to give way to his challenger.
This was an ironic twist on what went before. The previous generation of IndyCars had promoted undemanding throttle-pinned-to-the-bulkhead racing at any other ovals of 1.5 miles or more, but at Indy they were tricky, finicky beasts, the kind that could give even three-time Indy 500 winner Dario Franchitti the yips during a qualifying run. They were great.
