(Sorry for aggressive quote edit.)

Google Maps cycling directions include routes that go against the direction of traffic, even though cycling against traffic is illegal as is riding on sidewalks.

Apple Maps cycling directions take me to the nearest intersection of a destination and instructs me to dismount if the remaining leg would require wrong-way cycling.

Yeah Google also sends me through car tunnels to cross the river. These tend to be quite hazardous, full of exhaust smoke and without any chance to stop for whatever reason (tyre puncture, coughing my lungs out, whatever...).
