With the increasing number of people opting for cremation, fewer people practicing any sort of religion, I'm imagining hearses in general will become increasingly rare going forward. Although my family still attends church, I can think of four family-member (4) funerals in the last five (5) years where people born in the early 1920s were cremated, thus no coffin, no hearse.
The world and traditions of my childhood is rapidly disappearing. I'll probably opt for cremation myself, but that's more out of "distaste" for what becomes of your corpse over time, not because I view myself as a soulless meat-sack. Cremation seems more dignified when I compare it to cold, wet earth. Or maybe it's just because I hate being cold and wet.
