In an unfamiliar place I guess it isn't so bad, but knowing how long your drive should take while you're just sitting there going 5mph in between stops is very annoying.
I take surface streets all the way home now because at least I'm constantly moving and I only get trapped for one signal that I have to wait more than one-cycle of lights.
I let Google navigation guide me - it's pretty up on the traffic and is good to reroute you if there's a faster way to go.
