Please add an option to avoid unassisted left turns in North America. Difficult intersections helps, but doesn't help someone with limited confidence in making left turns whether it be from disability (limited range of motion), experience, etc. Many routes have slight deviations to make turns safer. This same logic may also apply to crossing a busy highway without a light. In these cases, it may make sense to make a right, then a left, and another right - if possible.

An option to route the driver to a left assisted by a stop light, or an all-way stop or a left that doesn't have a stop sign.
