Have to divide by number of airships, which probably makes them less safe than planes, if not cars. I think the difficulty is mostly with having a large surface-area exposed to the wind making the ships difficult to control. (Edit: looking at the list on Wikipedia, this is maybe not totally true. A lot of the crashes seem to be caused by equipment failures too.)
Your ‘accidents still happen’ link shows:
One airship accident worldwide in the past 5 years, in Brazil.
The last airship accident in the US was in 2017.
The last airship accident fatality anywhere in the world was in 2011 in Germany.
The last airship accident fatality in the US was in 1986.
I think that this compares favorably with very nearly everything.
