Well, yes and no. In a Vanagon a motion at 80 mph must be straight down and so the direction is known but not stated. So for a Vanagon speed and velocity could be considered interchangeable terms:^)

It's only velocity if you state the direction. Velocity is a vector
quantity. Otherwise it's speed. The two terms are not interchangable.
