> I kind of wonder if lawsuits/regulation might be the way to get those. I’m talking about prototype cars. The solution there to have an e-stop is to ask your technicians to put it on. No lawsuit or regulation is necessary for that. If you are thinking about mandating e-stops on production vehicles then I don’t think that is the right thing to do. It is a complicated analysis but it boils down to that the cases where it would help should be vanishingly small, and even in those people not trained for it would forget to use them. > there will always be some sort of cost with that kind of thing Absolutely. And the cost of the switch is not the major component. Where i work forgetting to reset the e-stop is so common that it is the first thing we ask about when something is weird. And the people forgetting them are skilled engineers with known prototype cars. I imagine the cost of support/service calls would be huge in prod.
