Description
A simulated route between 39.20037°N, 84.38027°W and 39.1997269°N, 84.3782329°W at 2× speed should make a sharp left turn from southbound Kenwood Road to westbound Montgomery Road. But instead of spinning counterclockwise, the simulation spins clockwise the long way around. Here it is having spun some 45° clockwise:
This issue doesn’t reproduce at 1× speed, and it doesn’t affect slighter turns.

Research direction
Start by reproducing the route simulation between the coordinates in the issue at 2× speed, then compare its turn direction with the 1× behavior and with slighter turns. Done means the sharp southbound-to-westbound turn rotates counterclockwise at 2× speed without regressing the unaffected cases.
