Ring cameras don't have continuous recording, they will only record on motion events. To my knowledge, there is also no way to set up alerting and capture preferences separately (ie if the camera detects motion and starts recording, you are getting alerted unless you turn off alerts for the camera entirely). If someone set their camera to record a public street they would literally get DOSed with alerts, so this is not what people do.

Also, to my knowledge there are very few restrictions on recording people in public.
