One of the most important off-road driving techniques is "starting in gear".
Rather than stepping on clutch and brake, starting up your engine, engaging 1st gear, releasing the brake and carefully letting the clutch out - there is a much safer way to get you started when the vehicle is in a challenging off-road situation:
Assuming you are in 1st gear low range (or reverse, low range) - step on the gas three times (not needed with fuel injection vehicles) - turn the ignition key and you are moving. Surprisingly simple.
Works in all cars with 4WD low range.
