The automobile industry is constantly making remarkable efforts to prevent car users to be hurt and to facilitate the operation of their products. Design of car bodies. Airbags. Reliability of components. Radars. Parking cameras.
Other industries, in simple or complex consumer goods, do the same. Telephones are recalled because one or two of them over 100 million might explode and hurt their owners.
But trucks manufacturers are still allowed to make and sell products that are not safe to operate because their drivers do not see around them. There are certainly plenty of ways to solve that problem, from cabin design to cameras through additional mirrors. But nothing gets done and cyclists continue to die.
The US being THE country of lawyers and big indemnification, how come nobody has ever managed to obtain a few 10s of millions and thereby force truck manufacturers to solve the problem ?
