investigating software

Thank you to the colleague/customer/product owner, who found the bug I missed. That oversight, was (at least in part) my mistake. I've been thinking about what happened and what that means to me and my team. Giving thanks. It helps us remember. I'm happy you told me about the issue you found, because you... 1) Opened my eyes to a situation I'd never have thought to investigate. 2) Gave me another item for my checklist of things to check in future. 3) Made me remember, that we are never done testing. 4) Are never sure if the application 'works' well enough. 5) Reminded me to explore more and build less. 6) To request that we may wish to assign more time to finding these issues. 7) Let me experience the hindsight bias, so that the edge-case now seems obvious!

Google Maps directs me to and from my client sites. I've saved the location of the client's car parks, when I start the app in the morning - it knows where I want to go. When I start it at the end of the day, Google knows where I want to go. This is great! It guides me around traffic jams, adjusts when I miss a turn and even offers faster routes en-route as they become available. But sometimes Google Maps does something wrong. I don't mean incorrect, like how it sometimes gets a street name wrong (typically in a rural area). I don't mean how its GPS fix might put me in a neighbouring street (10m to my left - when there are trees overhead). I mean wrong - As in something unfair and socially unacceptable. An action, that if a person did it, would be frowned upon. Example: Let’s assume a road has a traffic jam, so instead of the cars doing around 60 mph, we are crawling at <10 mph. In the middle of this traffic jam, the road has a junction, an
