→Best practices for different types of crossings
Why prevent U-turns?
* We do not want Waze to suggest illegal routing. Ever.
In some countries or states, U-turns are only legal when marked as such, but Waze will suggest one on each and every occasion where it thinks it is appropriate. (In Germany U-turns are allowed in most cases, except they are
permitted by sign.)
* Ad-hoc routing is better when U-turns are not possible.
