How about trying a little panning today. Panning is a way to create speed around a moving object, in this case, a car. The goal is to keep the car in focus while the background is blurred. To create this effect use a slow shutter speed. As you press the shutter on your camera move the camera horizontally following the car as it moves through the frame. If your camera has Image Stablilization (IS), turn it off. For the photo above I used a shutter speed of 1/60. Your shutter speed will depend on how fast the subject is moving so experiment and see what works for you.
If panning doesn't fit into your day today keep it simple and photograph any type of car that you might come across throughout your day.
