The Citroën Grand C4 Picasso is fitted with an electronic parking brake. Some drivers hate these electronic brakes, but we found that the C4's easily held the outfit still on a 1-in-10 slope. The brake releases automatically once first gear has been selected and the clutch raised to the biting point, but we found that the outfit would roll.
