Uncharted waters here.
But I’d think they could certainly go thru Tuesday.
The cars that will run at Phoenix have different chassis and engines. They are pretty much complete and sitting in the team shops.
They could eliminate Friday practice and make PIR a 2-day show.
It’s about 450 miles from Daytona back to the shops, and 2100 out to Phoenix. Likely about 50 hours driving time.
Yeah, I would bet that the haulers going to Phoenix are already on the road this morning in that direction - at least for the well-funded teams. In most cases, there won’t be an issue if Daytona has to wait until Tuesday.
The fans, though? That could be another story... not much they can do about it if rain continues... and there’s still a lot out in the Gulf of Mexico that’ll have to cross the entire peninsula before we’re done... today’s still a longshot.
