Hi, getting a new MG ZS this we,end. It’s coming by sea, a 14 hour journey kindly being brought up for me by a relative. They have asked if they should turn motion sensors off, as their own car has occasionally been very sensitive to a choppy voyage. The dealer thinks it’s a strange question, and suggest just leaving the door unlocked, but a friend thinks this may drain battery life for such a long period. Any advice, it sails tomorrow night?
