I know it's out there, but I cannot find it right now.

What are the recommend upvision and downvision angles (see image above)?

Aerohead has listed vehicle approach and departure angles along with the inside angles between the front and rear wheels - see below (forgive me if I wrote them down wrong).

Front: 10 degrees min.

Rear: 16 degrees min.

In-between wheelbase: 10 degrees min.

I'm doing a few sketches and the upvision angle (so driver can see traffic signals) seems a bit low on my design. Just want to check with some standards.

The math on this PDF is daunting.
