This would be a substitute for the pressure box. How far the pitot would need to protrude in front of the car to get a clean static pressure is the question.

That's a very interesting idea - one I'd certainly not thought of.
The two issues I can see though is that I think the static port would need to be a long way ahead of the car (eg 1+ metres) and such a support could change flow patterns on the car.
But, depending on how quiet your roads are, I think both are not major deficiencies. I'll give it a go today and report back.
