Er, that's actually what the article says. Ten years ago routing was done with fixed databases, whereby a "freeway" (motorway) was always deemed faster. Now it's done with live data, so if the freeway is recorded as slow by cars currently there, apps send you through residential routes. This creates problems for the residential areas, effectively scaling up "rat racing" problems to unsustainable levels.

The author studies this problem for a living, so I'd be wary of calling them up on receipts.
