We have a related problem in the UK. Sometimes very small "country lanes" have no explicit speed limit, so defaults to national speed limit of 60mph, which you would have to be suicidal to drive at (or just hate your car), but Google maps still often route finds along these roads.
An example:

- adav 6y agoWinding British country lanes aren’t a bug, they’re a feature!
- scoot 6y agoExcept that Google uses an average of the recorded speed of vehicles using a road segment, linked to time of day, and not the speed limit.
- Nightshaxx 6y agoThis. Google has a major advantage in that they have a massive dataset. They can use their data to improve the cost function even in real time to detect traffic.

- lemagedurage 6y agoSo they should add a "route options" -> "follow speed limits" checkbox, or track your speed compared to the average driver.
