Obviously it is a sad story for the deceased and it's family but according to the cruise spoke person there was supposed to be enough space so the emergency car could pass.
And later the article mentioned there were 55 more situations where these cars caused problems.
Well there are car accidents everywhere in the word every day because of careless drivers so this is kinda common.
So I really don't think banning these cars should be an answer, but to keep improving them.
