This looks like it is OSRM weirdness, but it might be a data problem:
This is very crazy with lots of weird loops, 12 turns.

But if I add one more position the looping goes away, Granted this
changes the exit strategy. but the next route does not.

Even this would be better, it is about the same time but shorter
distance and 9 turns compared to the first route.

The looping is what makes this stand out. I thought we had turn
penalties (but maybe they are not all that impactful) and that we should
get few turns for routes of about the same distance going through
similar via points.
