I would not assume that there is a Speed Bump any more than I would have assumed as a fact that the model helicopter task was a Fast Forward.
To me, it is speculation about the Speed Bump until we have express word from CBS in the promo materials, or there is a vidcap or photograph clearly showing that there is a Speed Bump.
One thing to keep in mind is that Bert and Elise are trying to keep us, and the Racers, guessing, by not doing the same things the same way any longer. We no longer have traditional clue boxes 90-plus percent of the time. We no longer have the location sign at the pit stop map. These last two seasons, Phil no longer introduces the last pit stop location at the beginning of the episode as "the pit stop for the previous leg" but as the "starting point" for the next leg. And they changing up the music at the end of the episode before the preview and closing credits with different music every leg.
In other words, the old line about Big Brother, "Expect the Unexpected" applies more and more to TAR. At least it is a concerted effort to keep things fresh without going for cheap melodrama between teams. (Racehl might be viewed as an exception, but then veteran BB watchers already know that Rachel needs to be taught some better stress management skills.)
