In my place (Geneva, Switzerland), Google Maps stubbornly keeps suggesting for years the fastest route form my side of the town to the other through one of few bridges that is actually absolute no-go for public traffic, with tons of warning signs (sometimes some of them are obscured by buses but still hard to miss).

Needless to say, there is often some sucker going through there, and I have to admit I ended up there once too exactly because of Google Maps. No effort to correct it over the years, in one of the wealthiest and most important power/finance centers globally.

What you and parent describe happened to me too, maps are absolute blessing compared to what was there before but they are sometimes not that great ie in cities with a lot of traffic. Its easy to get used to something just working and start demanding perfection, when we are maybe 96% there.
