While not space vessels by any conception, the miniaturization of the Diggs Coil permitted an anti-gravity field to be generated by successively lighter, cheaper, and smaller drives. With the Peace came the application of this technology to lighter vehicles, and the ubiquitous ‘jump truck’ became a common sight both here and on Mars. While too finicky for the general consumer market, they filled a valuable niche in the industrial and commercial sectors.
The narrow cab with the wide running boards we see here is some called the 'Mars cab’ because of it being associated with accommodations for bulky partial pressure suits. These typically had heavier framed windows and thicker glass, as well as the dual-stick setup usually associated with military craft of the period.
