I would be inclined to agree with extensive testing being desirable in this case. However, the only way I think that we're going to get a sufficient quantity of testing under representative conditions is to get a reasonably large number of these cars out on the roads.
We don't need to worry too much about their use in a non-testing context, I feel, when we look at companies actively pushing this stuff out they're either doing so in a highly controlled environment (transportation on mining sites for instance) or they're pushing it out in a highly limited form (for instance, self parking cars and lane keeping features.) Entirely automated driving is still experimental and the number of people who have access to it is still very limited, no-one's selling their current prototypes to the general public.
