Careful, this doesn't work when entering/leaving a city. I've done it dozens of times in my town because there's 3 fucking stop lights on the highway, yes highway, on the edge of town going 45-55 over a stretch of about 3/4 of a mile. There's more as you get further in town and the highway just becomes a regular road for a couple miles but by then you're in traffic and not as easily distracted.
