Social interaction is a major factor in preventing both physical and mental decline (which represent a huge economic cost to society, as well as social and personal cost to the individual). Travelling as the only passenger is a vehicle will not provide the same stimulation and may cause anxiety, which leads to a preference for inclusive services, covering all users including those with access needs. Also, the ability to travel with a companion (at no extra costs) would help with this concern both for older people and for those with mental health issues or learning disabilities.
