In physics, the formula for momentum.

Sydney had to be reminded several times that a vehicle carrying four adults
plowing full speed may not have the agility to turn quickly or to stop
short. Usually, the four of us screamed and mom spun her fake steering
wheel while Sydney gave us the deer in the headlights look.

Also, the fake steering wheel on the passenger side never got old.
"Turn faster mom, turn faster! We're gonna crash!"
Eventually, I sat in that seat and must admit there is a strong
urge to assist the driver in steering. We agreed mom needed
a thumb-bell and a squeeze horn for the full effect.
