I don't think that's true. Google maps uses average speed on roads to estimate the fastest route, not the speed limit.

If they used the speed limit the app would never take traffic and other conditions into account, which it clearly does.

Having said that, I have experienced a crazy route now and then, but I think it's often caused by incorrect map updates.

Even in the U.S. Google Maps regularly recommends things like unprotected left turns against heavy traffic to get onto a road with a speed limit which is 5-10mph higher, even when that road is equally congested.
