Of course it causes a new error.

If I go to my output for 100 steps, I find that the y value is between 0.7 and 0.9.

0:00:10.000,0:00:13.000
It really a lot of error.

Put differently, the robot oscillates a bit like this with a fairly constant

0:00:18.000,0:00:21.000
new offset error due to this bias.

0:00:21.000,0:00:24.000
Even though the bias was in steering, it manifests itself

0:00:24.000,9:59:59.000
as an increased crosstrack error in the y direction.
