Can the vehicle make the turn and how the hell do you figure that out.
When turning, the inner, rear wheel is on the turning circle, and is oriented on the line tangent to the circle at that point.
1) Draw your vehicle.
2) Create a circle that is tangent to the inner, rear wheel, and to scale.
3) Draw 2 circles, concentric with the constructed circle.
3a) 1 of the circles inscribes the vehicle.
3b) 1 of the circles circumscribes the vehicle.
The constructed circles represent the minimum wall spacing through which a godly-skilled driver could just barely scrape both walls getting through.
EDIT: for a rectangular car, with no overhang, and the wheels at the edges, step 3a is identical to step 2.
