Merging into a freeway is about the only time I would pour on the gas and that's only to reach the speed of the traffic flow before merging. Past midnight when traffic is light here in town, I take my time and stick to the city speed limit (40 mph/64kph). I haven't had a need to be in a hurry for a long time.

I do get frustrated sometimes when a 6 lane road suddenly becomes 4 with little warning and I'm on the slow lane which is the one that merges. That's why out of experience, I always stick to the middle lane of a 6 lane road.... peace of mind.
