Thanks for the link. Interesting info.
This is in part the reason I am considering building my own, one or two seat, microcar (after the mini is done of course). I thought about doing aero mods on the pickup, but it is rarely used for commuting, and more for actual truck duties. So instead, I thought I would put the efforts towards a dedicated, all weather (within reason) three wheel, lightweight, and aerodynamic, commuter.
