Perhaps, but what it may spur is a continuation of a growing trend in automobile design to make large vehicles more crash-friendly with smaller vehicles. One effect of this trend is the lowering of the effective bumper height on large SUVs and trucks to decrease the incidence of bumper override during truck/car accidents, and to allow a greater chance that the truck will strike the more reinforced areas of car doors in the event of side-impact collisions.

However, it is difficult to overcome one cold fact of physics: If two objects collide, the object with greater mass will decelerate more slowly than the other object. As the chance and degree of passenger injury generally increases with the rate of deceleration, the F-150 will always win over the Focus, as long as the truck doesn't roll over.
