I design driveways, and 20% is the max allowed. I've seen 25%, and that's pretty darn steep. 25% requires grooves in the concrete for traction. 38%? Wow. Did I mention that's ridiculously steep? The steepest hill in San Francisco is Filbert Street, at 31.5%.
How long is the driveway? Can you measure the vertical change across the horizontal distance? Percent slope is vertical divided by horizontal.

Thanks guys. The expertise here always blows me away.
I honestly don't know whether the thing is 21 degrees or 21 %. We spoke in terms of degrees — but this was in German etc and it may well be percent. I will clarify this asap.
Can I assume if we are actually talking percent, that I could live with this grade? Car is a stock 997S.
