There probably were some kind of limitations or human interactions thrown in.
Maybe they got the car on the autobahn, got it going, then turned it over to
computer control for a long straight stretch to see how fast it would go. I
haven't really looked into it though. In this article Dickmanns is quoted in the
mid-90's apparently saying that it would take more computer power to have a
truly "do it all by itself" car:

I think the first DARPA event failed mainly due to lack of testing and
development by the teams involved on the kind of real world off-road course they
had to face. Some got thrown by mechanical problems, most got thrown by their
code not being able to deal with certain kinds of challenges that the off-road
course had. With more experience they were able to refine their code to handle
all the gotchas for the second event.
