"Most" might be true but it certainly doesn't apply to all. Uber's self driving car recently killed someone and there are plenty of indirect examples of deaths like the reported suicides after Mt Gox collapsed. Either way, "it isn't going to kill anyone" shouldn't be an excuse for ignoring the law or reasons for why that law might have been created in the first place.
The same logic applies for a majority of cryptocurrency and gig economy startups.
