I would like to suggest that Waze use a notification on Brazilian roads, similar to the ones already in place for speed bumps and potholes, to indicate the presence of a third lane on highways.

This would be very helpful since many roads in Brazil do not have dual lanes, and when a third lane does appear, it is extremely useful for all drivers.

Additionally, this notification could help reduce overtaking, as drivers would be warned in advance about the third lane ahead, allowing them to avoid unnecessary overtakes, thus reducing the risk of accidents.
