Yeah, the phone just sticking to the seat was surreal. It's hard for me to imagine that kind of acceleration (and I've owned some quite fast cars).

I liked the "oh, I probably shouldn't have been texting right there" look on the girl's face and the fact that her brother laughed at her for it.

I once owned a 1968 GTX with 635 HP. The closest thing I could compare the acceleration to was taking off in a jet. It would bend back the racing seats on launch so it may've been able to produce this result.
