At this point it seems meaningful to describe behavior as "evil" if it's relatively easy to identify that your algorithm is working badly or producing bad/dangerous outcomes but still leave it running as-is. Do small scale tests until it's fixed instead. Driving cars is dangerous as-is, it's not going to be great to send thousands of people down residential roads that might be less safe than arterial roads AND make them drive worse by frustrating them with bad traffic.

I share your experiences with Google Maps and Waze giving me bad or actively dangerous directions. I learned to distrust those apps as a result.
