Here is a couple of questions. Just being the devils advocate here.

1. Is the car actually capable of going -1.20+ under?
2. Was the car properly classified? Sometimes a car will show up on the Q sheet in the wrong class and show it was farther under the index than it really should be. Typically on the first round of Q. Happens a lot here in D2 on the first Q run.

3. Is there a chance that the clock malfunctioned or some blowing debris or trash tripped the beam?

These are a few things that can cause an erroneous ET on any run at any time.
I don't know the car or person that was involved and don't see anything but rumors here.
