It isn't too much of a stretch to say that the Rapid Delivery Vehicle could very well be the delivery truck of the future. Designed by Leighton McDonald, the Rapid Delivery Vehicle (RDV) is a delivery truck designed to expand and contract based upon its cargo.
The RDV has a small cab and an extendable chassis that can double in size via remote control. The result is a full-sized delivery truck when you need it and a small, space-saving vehicle when you don't. The smaller form of this vehicle could be used for navigating crowded city streets between deliveries, or for delivering smaller parcels that don't require a cavernous cargo truck.
