New Fast and only city driving

Okay guys, I bought my fast a little over 3 weeks ago. The first weekend I took it on a road trip over 300 miles away. Since then, I've only had a chance to drive it in town. It's driving me nuts. I only live about 4 miles from work. By the time I punch it, I'm already at work. Its a 35 zone the entire way and I'm finding it difficult to keep it under 45. I find myself at night staring at it, wanting to take it out for a spin. >
