Aerobus has not been installed and operated publicly since Mannheim. The reasons for this are both simple and complex:

In general, the urban transit market is highly conservative. Because of heavy public and political exposure, transit operators prefer to buy only hardware systems which are well proven and tried by another user. This has presented a "Catch-22" situation for all new technologies. There has also been a long standing fear of complicated, hi-tech, aerospace-type systems.

It was no accident that automated people-movers, monorails, etc. first penetrated the Airport and Amusement Park markets. These markets have personnel and institutions well acquainted with high technology and constant innovation.

In the case of Aerobus, its inventor, Gerhart Mueller, died shortly after improvements were made to the system. The patents and technology were acquired by VEVEY of Switzerland. They recognized that they had an ingenious cable suspension system but no production vehicle, so they concentrated on the design of a vehicle family by the combining different size modules. VEVEY also conducted a worldwide marketing campaign and in the mid-80's obtained a commission to design and install a 7 mile system in Kuala Lumpur, Malaysia. Malaysia, being one of the aggressive, Newly Industrialized Countries (NIC), under-took a very intensive privatization effort. However, financing for the Kuala Lumpur Aerobus collapsed, leaving VEVEY at the verge of building their own demonstration facility as part of their product development effort. The extensive design and marketing costs and the losses incurred under the Malaysian cancellation forced VEVEY out of the business. This resulted in the acquisition of all Aerobus patents, drawings, studies, know-how, records, the Kuala Lumpur designs, specifications, etc., by Fred Parks, a highly successful, entrepreneurial Texas attorney.
