90 year old Queen Elizabeth drives Kate Middleton around her Scottish estate (photos)

The Queen of England may be 90, but she proved on Friday that she can still chauffeur family members to gatherings at her beloved Scottish estate. The queen drove her granddaughter-in-law, the Duchess of Cambridge, Kate Middleton to a picnic lunch with Prince William in the hills above Loch Muick on the Balmoral estate while the security guards sat in the backseat behind them.
