The twitter thread is the worth the read because it debunks several popular justifications to not change. (I.E. multiple winners of TC have done it at different setups and my favorite "don't fix what's not broken." First off every aspect of racing is broken. This is just less broken. Second, both MLB and NFL have made massive changes to their games when they were the biggest game in town (interleague play, DH, playoffs, divisions, overtime, DH, etc.) Successful businesses understand you need to constantly change to stay ahead. Meanwhile sports like boxing and golf have stayed traditional. how's that working?
