Major Vehicle Parameters

This page, and subpages, will be dedicated to exploring and settling on major parameters such as kingpin, caster, scrub radius, CG, wheelbase, etc.

Designed steering to pass regs and self-aligning steering, not much else. Wanted to simplify while maintaining efficiency so everything else was close to 0
