Autorollaphobia is the fear that the "driver" of the vehicle of which one is a "passenger" will not slow or stop in time and crash into the vehicle(s) that have slowed or stopped in the road ahead.
1) My passanger
who I beleive has "autorollaphobia" shouted "Stop!" as I slowed my car
to a stop in traffic at the intersection
. "Would you like to drive?" I asked?
2) My autorollaphobic passanger
shouted "Back off" as the freeeway
traffic and my car slowed to view the roll-over accident
near our exit. I said to her "Maybe you should drive from now on!"
