If you take the car transporter train thru the Chunnel, you will find yourself driving on the left, in a left-hand drive car. Unless you have A LOT (as opposed to none whatsoever) of experience driving on the left, I do not recommend this. Sitting on the wrong side is one of the ways we subliminally remember to drive on the wrong side. Do not drive on the left for the first time in a left-hand drive car. Unless you have truly EXCEPTIONAL powers of concentration it will be dangerous.
