13. Only about 85 feet long AND did not have the computer program to make sure wheels follow wheels

Furthermore Renault/Heuliez only sold 10, and in 2004 was replaced by a Streetcar/Tram/LRV:

The problem with all of them is that they all lack the computer program that keeps the wheels following each other, in these older system, each section will turn inside the previous section. Thus, at best can only be used in limited locations, for example Bordeaux only purchased 10 and then only in an effort to fight off the push to install a Tram/Streetcar/LRV system. In Brazil, where these are popular, they run on dedicated right of ways that makes sure the turns are within the capacity of these extra long buses.
