      • Uses
        • Help plan events
        • Farmers need to organise their crops
        • Transport companies
        • Everyday use - need an umbrella?
        • Council - need gritters out on the roads?
    • Car crash test analysis
      • Examples of inputs used
        • Speed

        • Brake conditions
        • Direction of collision
        • Number of occupants
      • Avantages
        • People don't get hurt
        • Less expensive and safer - don't use a real car
