Who'da thought this would be 50 times harder than a stick shift? It seems to be overly tricky and I'm quite nervous because of the car's varied responses to my attempts to back it onto my ramps. With the door closed I can't see as well so my wife has to give me progress reports. With the door open it frequently just quits responding and I have to enter park and restart. Modulating both pedals has various responses like vehicle on incline, removed power from motor, Reduced power to motor Hold doesn't work predictably and creep won't creep up hill backwards. What ultimately worked was 1. put on brake and hold it 2. put in reverse 3. touch accelerator until both pedals engaged and the both pedals warning just comes on then hold the accelerator there 4. release brake and hope car remains stationary on the ramp slope 5. press accelerator 'til car reverses and hold it steady 6. car will stop moving and roll down if you vary the accelerator and your progress will be restricted to about 6 inches per attempt. 7. go back to #1 and repeat 'til you reach the top of the ramp. Maybe I just need to be more trusting but I'm not in a trusting place yet with ~400HP under my foot and this disconnected drive-by-wire feeling. Has anyone found the secret to doing this? Sorry if this has been answered but I couldn't find it. I need to clean out the rear under body panel and thought this would be easier than setting the rear up on jack stands.
