In all honesty, I thought this feature was already active, but then I don’t drive, so what do I know? Nothing, clearly. Anyway. The Google Maps team has added live traffic information to major roads in England. Just England – no Scotland, Wales or Northern Ireland just yet.
If you enable this layer on your maps, it’ll tell you what traffic conditions are currently like, as well as predicting what traffic will be like at any particular day and time, based on past conditions. Nice, Google. Now roll out Street View, please.
