I would worry less about drink drivers.

Live your life is my advise.

Reality is after handing over the site it'll possibly die anyway.

Seriously, not having your own burial arrangements, design headstone and plot already paid/picked out is nearly as bad as people whom selfishly commit suicide, get into drugs and/or make their lives trainwrecks and shift the costs, burden and agony onto the living. In the mortuary industry, it's called "pre-need" and it's way cheaper (adjusted for inflation) to get it done in today's money than decades later. Plus, there's pre-need cremation for those whom don't want to go in the ground in a vault+casket, which also cheaper.
