And presumably the lorry driver will pay a little more attention to low flying aircraft signs in future!
Having said that, I think the point was probably well made that it might have been appropriate to be little higher as you crossed the road if traffic was visible. (But, isn't retrospect wonderful. You were flying a flapless approach, with a mildly unhappy pax, in a jet with poor ergonomics and a very high coaming, I don't suppose it was high on your "to do" list).
Nice looking jet.
