I have some sidewalks that the reverse back is on instead of turn zero.
At times for dead ends it will start the sidewalk in reverse! Instead of getting in snowblowing and out in reverse. Getting stuck when it does this of course by reversing into snow. My sidewalks were programmed in the right direction.
This has been reported multiple times. They are working on it.
Probably wouldn’t hurt to still put a ticket in so they get the sense of urgency 
Hi there, sorry to hear about this issue. We’re aware that there are some bugs related to sidewalk behavior, and our team is actively working on fixes. That said, we can’t be certain yet whether your case is caused by the same underlying issue.
We’d really appreciate it if you could submit a support ticket and include the approximate timestamp of when the issue occurred. That information will help our team investigate more accurately.
Ticket submitted with screenshots examples, I think this happens when entering from a sidewalk to a sidewalk.
