"We Blew it"
In Driving Visions, Laderman states that "at a certain point down the road, the road movie's glorified mobility seems to yield a disillusioned attitude in the protagonist, who have been unable truly to escape, and who have internalized (brought with them) the pressures of conformist society." This quote seems to help explain Wyatt's "We blew it" statement in the fact that neither Wyatt or Billy ever escaped conservative and conformist America despite all their efforts. For instance, at their last campfire conversation Billy says now that they have all their money they can go to Florida and retire. This statement is reinforcing the ideals of conservative America where you do settle down and have a sense of stability. At this point in the film, Wyatt is no longer "disillusioned" from traveling on the road and realizes that they never did completely embrace American counterculture but were stuck with the beliefs of conformist America. Indeed conformist America literally kept following Wyatt and Billy while they were on the road - one example is when the men in the diner follow them to their campsite and give them a brutal reminder of the conservative America they are trying to escape from. Another instance is of course at the very end when the pickup truck, another symbol of American conformist culture rather than a motorcycle, chases after Wyatt and Billy showing that no matter where they go the conservative American culture will always be with them. With this last sequence in the film, with the exploding motorcycle and two deaths, we get an extreme visual of the counterculture ideals dying and in the end the conformist culture conquers. When Wyatt says, "We blew it" he finally realizes that no matter how far they traveled the conformist culture will always be with them.
