There is already a backup plan for a race to be held in Europe, probably April time, if Sebring doesn't happen.
My worry with Glickenhaus is that they have had plenty of time to get at least one car built and tested, let's not forget the HyperCar regs were due to start at Silverstone last September!
I just hope they aren't going to turn up for Spa and Le Mans then disappear as others have done before them.
