Google Maps has reinstated the feature letting you know how long a trip will take in current traffic. According to Autoblog's sister site, Engadget, the previous algorithm didn't pass muster, so the updated calculations uses both historical and current traffic conditions to arrive at an estimated time of arrival. It appears on the journeys for which information is available beneath the no-traffic estimate.

Drivers of late-model Ford vehicles equipped with Sync Traffic, Directions and Information (TDI) will soon be able to plot out their routes using Google Maps on their home computer and then download turn-by-turn directions directly to the car. TDI is a recent addition that adds a GPS receiver which allows Sync equipped cars and trucks to provide directions even if the vehicle doesn't have the full map based navigation system in place.
