Driver or Passenger
It's not just the driver who can stiffen up in a car.
Passengers are often seated for long periods of time in a fixed position.
Movement is the key for car, driver and passenger.
As a passenger, try to alter your position from time to time and sit with your knees bent and thighs level and comfortable. Avoid sitting with your legs crossed; move them regularly.
For driver and passengers, stop regularly especially when feeling tired. Get out of your vehicle and walk around it several times.
Stretch like a cat, gently moving your arms around, bringing your knees up to your hips, and stretching your whole body.
