Today I drove from home to church and back home.  From the moment I backed out of my garage, I was accelerating.  I had a low velocity because I didn't want to hit anything around me as I was in reverse.  When I drove in the residential areas I remained at a velocity of +25 mph, but when I reached Kamehameha Highway, I accelerated to reach 35 mph.  Of course, since I'm just beginning to drive, I did not accelerate at a constant rate because I kept jerking.  Each time I came to a stop sign or stop light, I gradually accelerated negatively until I came to a complete stop at the stop line.  Also, whenever I reached a turn I had to step on the brake and lower my velocity so I could remain in control of the car and turn safely.  After church was over, I drove back home and pulled into my garage.  At that point, my displacement was zero.
