———————————————————————————
In the UK, and probably other countries as well, there are lots of narrow roads, usually with high hedges on either side, that can only be used safely at a low speed. These roads don’t normally have a posted speed limit so the route software treats them as normal roads, when in reality, they should be avoided unless there is no other option.
