I'm not convinced that leaning forward gives us that much more visibility. We do it instinctively when there's an obstruction, but it likely doesn't help unless you also creep the car forward. I have 3 obstructed T intersections just getting out of my neighborhood, and at the point where I want to lean forward, I purposely stop the car before the front end crosses the end of my road. Can't see. Lean foward. Can't see. creep car into the intersection. Can barely see, and if there's someone barreling down, i'm slamming on the brakes and hope they have enough control to swerve or brake.
-edit-
I have been very tempted at times to sneak out at night with an electric (quiet) chainsaw and just cut down all the sh*t obstructing these intersections. I can't believe the property owners would allow this to happen. surely they have to deal with the same damn blind spots.
