Steep driveways here are a proper test, and a jacking problem
Streets falling toward North Harbour and Manly Lagoon have driveways at real gradients, some of them turning as they drop. For safe jacking we work on the street or a level apron. For testing they are ideal: a steep driveway loads the handbrake, hill-hold and low-speed clutch or torque-converter behaviour, and the scrape marks on the apron show whether the car has been grounding its front lip.
