I wish they would wave a purple flag at the of the stages and keep racing. No idea why a caution is needed with the 10 or more minutes between stages.
Road courses are going to be stupid.
The All-Star race will have 2 tire compounds, a soft and a harder compound. The soft tires have better grip, but shorter life, while the hard compounds are the opposite. Each team will have 1 set of softies and rest are the hard tire. The only rule so far is the tires can't be mixed.
And a prediction for next year - The hard and soft tires will be the norm next year.
