How Do The "Helpers" Get To Their Jobs?

The first time a curious toddler wonders why four people in red suits and white beards are on the same block, the parent (or whatever adult is accompanying the kid) might explain it this way:  "They're Santa's helpers."

Now, when Santa is shown on his sled towed by eight reindeer, we never see the "helpers."  Even though I stopped believing in Santa Claus, probably, the day I saw four (one of whom was Black) on the same block of 18th Avenue in Brooklyn, I still wonder how those "helpers" get around.
