Answer: The standard vehicles included in guidelines are defined to be more conservative (larger dimensions & reduced steering capability) than realistic vehicles given its intended purpose is to ensure that most vehicles in its class can be accommodated by the design. For these vehicles, it is likely that the deviation will fall within the swept path envelope if the trajectories are similar. If you are modeling realistic vehicles (i.e. vehicles created following manufacturer specifications, we have performed field tests to validate the behavior of actual vs simulation (AutoTURN), which results in off-tracking of within 3% of the maximum swept path width.
