Road Wars

Road Wars will help train you to be a SMOOTH driver, which will lead to less car sickness and reduced motion for your passengers, including your pets (which usually are NOT in seat belts)
RW grades you for a drive, and allows you to email the driving stats. Grading is based upon the extent of head-jarring forces exerted by how the driver is actually driving. (g-forces)
SAFETY IS ALWAYS PRIORITY #1, AND ALWAYS WINS OVER PASSENGER COMFORT.
So, don't worry about your passenger spilling their coffee all over themselves if you are going to hit car that just pulled out ahead of you.
When driving:
Press the applicable pedals slowly, gently and smoothly
Keep a safe distance from the vehicle in front
Read the road and anticipate changes that you will need to make in advance
Chill out and keep calm
Don't try to beat the other cars at the lights or any stop
Indicate and signal early
Steer precisely to keep within your lane.
The advantage of driving like this is that it will save fuel as well as giving your passengers a comfortable ride.
T0 Use Road Wars App:
Secure phone in car, do not handle while running Road Wars app
While driving, secure the phone (just putting down is fine). Do not handle for anything, until app is out of driving mode, or app in suspend mode.
Just drive, and let Road Wars be your reminder to drive smoothly.
Keep your needle in the green, and your passengers will thank you
So, don’t drive like Elaine and get your passengers sick (see the About view in app) , and drive like you have a bunch of puppies in the back seat.
Remember, drivers rarely get car sick (drivers know every move), it's the passengers!!!!!
(Technical Notes…)
Road Wars is calculating a G-FORCE value for the motions that commonly occur in car….Acceleration, Braking, Turning Left and Right. 
RW use the iPhone’s accelerometer to accomplish this, and uses the iPhone's motion chips to decide if you are driving or not.
