If it because of acceleration, the effects of 1.1G (launch) you are experiencing the normal results. After our initial test drive (a few launches) I was feeling sick. I commented to one of the twenty-somethings back at the showroom about the motion sickness and probably my age. He smiled and said that everyone gets sick it just depends on the number and frequency of launches. Google the effects of 1+ G on a human. After a few times of launching our P90DL I would rather have a few more miles of range vs the 2.8 sec launch. 3.1 is plenty fast.
Turning on the rearview camera while going forward is not fun either.
