Dead-man switches do not work.
- SilasX 9y agoDon't work for what purpose, according to whom? Are you sure that applies here? What I suggested there isn't really a deadman's switch ("stop if no one is around to do task x"), but something to periodically, randomly check the driver's attentiveness, and can raise a red flag if they take too long to respond. A deadman's switch is different and enforces "do X if person Y stops doing this thing at this predictable interval" -- not what I was proposing.

- SilasX 9y agoI was proposing it as a way to validate engagement by the testing teams, not the mass market.
- blattimwind 9y agoLike I said, these are especially hard to get right for frequent users, presumably your testing teams would log a lot of hours on these - just like train drivers, which have had this exact same problem.
- SilasX 9y agoYes, you said it several times, just not with a citation or other means of grounding your claims that might lead us to a way of resolving the disagreement productively.
