I went to Sebring to see the testing yesterday for a few hours. All the drivers looked like they were pushing pretty good. I saw on Racer de Vries was quickest even though he did a lot fewer laps than the other guys. Vandoorne must have run most of his laps early in the morning because I only saw him on track for about an hour. I mostly saw Aitken and Ilott out there.
