Well, now there, @
cat94, I have a similar situation.
My driveway is not only steep, it has a crown where the driveway meets the sidewalk.
In order to not scrape the underside, I have to hit the crown at a 45 degree angle, without a passenger (my car is stock height).
So, when backing out into the street, because of the crown and blind spot, I have to go very slowly, since it is up hill ......thus slipping the clutch quite a bit.
I have taken the car in and out every day, for the past 4 years and my car's clutch is just fine.
Not to worry.
