Technology exists for the vehicle to not only kneel but to move both up and down 6 inches. This 12 inch sway could provide level boarding from most curbs with a small slide out ramp to cover the gap. Eliminating an incline which is difficult to manage for some users. From a universal design perspective this could meet the needs of all vehicle passengers. If a shuttle AV is being considered this would be a key differentiator to existing vehicles. Additionally if the vehicle could be made aware in advance of the passenger needs it could pre-emptively act accordingly making boarding more efficient for all. In particular it would be an inclusive experience for those who may need more boarding assistance.
