The suspended vehicle with tethered and untethered cargo and compliant tires can experience road features including full width speed bumps, half-side speed bumps, and variable gravel road sections.

Features:

- at t=0 the vehicle drops a short distance to stabilize the suspension. That short response will show up in the acceleration plot.

- speed bumps can be full width or half-widths with user given height and width

- multiple speed bumps can be given

- gravel sections can be defined in amplitude and length

- vehicle parameters and speed are user given

- several vehicle location vertical accelerations are plotted including a user given location

- the vehicle response is shown dynamically

- the untethered box is free to bounce around and even fall off the vehicle and bounce on the ground
