Can you imagine - all the cars carrying the family friends and relatives following the hearse - then the hearse floors it - and everyone trying to keep up - would certainly spice up funerals. Inside the coffin they could screw in a hook on the bottom and thread a belt through it and around the waist to secure the body from breaking out of the coffin - or even better, a solenoid operated coffin release system, an auto opening boot and a quick reverse to the grave with boot open and solenoid released - a stab on the brakes after reversing and coffin deposited direct to the hole, simple, quick and funeral directors could handle more jobs per day.
