I once had a serious learning experience driving from the suburbs into the CBD to meet friends. My attempt coincided with a Zombie Walk that bisected the city. It took me forever to reach where I was meeting friends, then another forever to find somewhere to park the car (all the paid parking was full) given I had to radiate out and cross the zombie parade again. Took 90 minutes to do what would've taken 5 minutes normally, or maybe 10 minutes on foot. All for one person in a car.
