This one's a tricky one to explain. Sometimes, I'm on a highway, and Waze's suggested route goes out onto a very backed-up exit ramp that backs up a half-mile before the actual exit ramp begins, occuping the right lane of the road, even while the other travel lanes are moving at full speed.

I'm trying to figure out if this skews the traffic routing and travel time estimations. Yes, the highway is backed up and traveling at 2 MPH, but only in the right lane where that exit is backed up half a mile. If you're in the center or left lanes, you're moving along at 40-50 MPH.

Unless, of course, you're one of those drivers who waits until the last possible moment, cutting everyone off right before the exit, at which point you're causing a center-lane backup.

I think what I'm suggesting is to ensure time estimates are based on the travel lanes that comprise that specific routing combination, based on travel speed if a particular exit IS used, versus travel speed if that same exit is bypassed.

I'm not sure this information is accounted for in Waze. I remember at least once, taking the suggested routing, but ending up in one of those right-lane backups as my arrival estimate crept up another 10 minutes.
