Mirror Needed at Intersection

Harris St is a narrow sloping ramp with cars parked along one side constantly and only 2 driveways to move into to avoid oncoming traffic coming out of Elizabeth St which is a blind corner. When turning right out of Elizabeth St if confronted by a vehicle coming from Harris St one has no alternative than to reverse into Elizabeth St. However depending on the speed of either vehicle this is often very sudden & dangerous even for cyclists. Perhaps a mirror at the "No through Traffic" sign would solve this problem.
