Yes, I can see how someone could consider it useful, but that always needs to be compared to alternatives and downsides. For example, the government knowing exactly where I am at all times could be useful if I get abducted or something, but there are so many potential downsides and limited upsides to that to the point that I can't consider it a reasonable option, therefore it's DOA.

So yeah, I don't see location sharing as net useful, especially when the alternatives are almost equivalent in convenience and successfully solving the problem. My routine is the same almost every day, and deviations are really easy to communicate w/ a quick text.

Location sharing is a solution in search of a problem.
