In your private car, there should be no need for you to carry such an item, and can't imagine why you would need additional insurance for doing so.  I would, however, restrict its use to family members who have waived their right to compensation of any sort if they are injured in use of the lift.

Three on Three link is our link video series where we compare watches from different brands that link share a lot in common. Here we have Grand Seiko going up against two longstanding stalwarts of horology: Omega and Rolex. That those two brands are legitimate competitors should tell you all you need to know about GS quality.
