Any idiot with a heavy foot can drive fast. Hell, you see these morons out there on the road every day. Accelerate hard to a stop light and then punch the gas as soon as it turns green. These are the same people who hug your bumper in traffic, even when it's a total logjam. They don't allow any room between cars, speed up at every opportunity and exceed the speed limit on highways beyond what's reasonable (more than 10 mph). Oddly, they don't actually get to their destination that much faster, as studies show. In fact, it's been proven that only car trips that go more than 500 miles benefit from driving faster. 

Oddly, they don't actually get to their destination that much faster, as studies show. In fact, it's been proven that only car trips that go more than 500 miles benefit from driving faster. Any gains made by additional speed in everyday driving are usually scrubbed out by traffic lights and vehicular traffic. This is why the person driving the slow hybrid you blew past five miles ago is now ahead of you. So, what's the point of trying to drive fast when you're only making gains in your own mind?

You're also wasting gas, putting unnecessary wear and tear on your car (especially the brakes), and you're also putting yourself and others at increased risk. And don't forget about the financial ramifications on the legal end. Smokey doesn't like speeders that travel 10+ mph over the speed limit, so if you get caught speeding, your commute will be even more hampered. And then there's the cost of a speeding ticket, which will make things even worse.

When you take into the account that speeding really provides no practical gains, it may just slow you down enough to relax and accept the fact that the risk isn't worth it. Resolve to drive smoothly in traffic, by allowing good following distances to keep braking to a minimum, merge well by letting cars alternate, and don't put yourself in the position of causing any ripple effects in traffic. The world will be a better place, and your commute will only have served to give you a chance to relax.
