Safety products have a hard row to hoe in the market because it's always more money up front to avoid costs that might not occur later, and it's full cost sunk immediately, not a small monthly price like insurance. When the guy who invented the auto-brake table saw got no traction in the market, he tried to get insurance companies to require it of wood shops. I haven't checked in on that story lately. It was a really difficult sell, because when the saw braked there was a large assembly to replace, in addition to costing more up front. So "false positives" were very expensive. But real positives prevent losing fingers. Lots of times this is solved in reality by having the government take care of it, with regulation.
