Have looked but can't find a math or physics NG that will help on
this, so turning to the NG that Knows it All.
Problem: Looking for a formula that will yield angle of vision
subtended by a driver in an average sedan, varying with driver's
height. Specify "normal" torso vs. leg relationship. (how get this?)
Ex: Driver 6' tall will see [angle]. Driver 5''7" will see [angle].
Driver 5' tall will see [angle]. Driver 4''9" will see [angle].
Not sure how to clarify "angle". In lay terms, I mean what area is
covered by what [driver] can see. Taller driver will obviously see
more than short driver. Is there a formula?
Referrals to helpful sites appreciated.
The whole point is to derive a formula that can be plugged in for <x =
Don't see that "hood height' need be only variable; driver could be
looking out of side window as well.
Sigh! This is more complicated than I thought!
Chuckle. As a kid, I remember regular complaints in the hilly parts of
southern Indiana, that the no-passing zones on the winding 2-laners,
were way too short. Turns out that the start and stop points were
figured by a tall guy in a pickup truck, and short people in cars were
taking it on faith that they could see and be seen by oncoming traffic.
Not sure if anyone ever died because of it, but eventually a lot of them
But for seat back angle, you just need to include theta, or sin theta,
Not the same thing, but it's either Pa. or Md. that has hills you
can't see over on almost-two lane roads. So you'd better darn well be
all the way to the right. Pa. has a bunch of hills that were cut off
at the top on those roads, but I think it also has the hills you can's
