But if you just go to golf resorts door to door, and have a garage at home, they are probably the easiest to use, the easiest to load with their clamshell design, and the most protective.

Functionally obsolete is a different story, Stidger said, explaining that bridges carrying this tag also carry major design problems, diminishing their load-carrying capacity.

The advantage of this arrangement is that it can be scaled up more easily than a semi-rigid design, since the envelope is not load-bearing.

The group said the new design would not affect the amount of load carried by the lorries and the lower cabs would encourage safer driving.

Sorger took a page from his days as a pilot and applied a weight and balance equation to the design, shifting a larger percentage of the load toward the rear wheel, which improved both handling and stability dramatically.
