Incorrect display of scooter legs

This issue has been found intermittently and has been hard to replicate. Sometimes the eScooter leg will double back on itself for no known reason. OSM has been checked and verified (that it isn't the cause) in at least two of the instances we've found. Not fully confirmed, but this will often appear with the eScooter leg is the second leg (after a walk leg) in an itinerary).

In this example, see the third option (but note that it may not return the same results):

As it was described to me "Walk down the block to pick up your scooter, zoom back and forth a few times to test it out, cut across your neighbor’s lawn"
