There are no modern vehicles available (that I know of) that do not have the usual caveates regarding cruise control operation in the owners manual... If there is a defect in the car, it is in the fact that it will allow itself to be driven by someone unfamiliar with the contents of the owners manual.
What most people need to realize is that a car is a piece of machinery... nnothing more - nothing less. Operate it unsafely or operate it without exercising due care and attention (like, maybe, detereorating road conditions) can and will have life altering consequences. The sooner people return to accepting the reponsibility for their own actions or omissions......
Every time they make something more idiot proof, we cultivate a "better" breed of idiot...
