I thought my flying number 25 bus was OK given I had about eight minutes to design it. Yesterday I came across two inspiring collections of future vehicle concept art: Firstly, the BBC reported on this attempt to redesign the ambulance as an off-road vehicle with ejector seats to launch paramedics into the thick of the action, along with other innovations. This is taken from an art exhibition that has unfortunately now finished.
Secondly, Dark Roasted Blend reviews this book of sci-fi art by Daniel Simon. No further comment.
