We live in the city, a large crowded city. We take public transportation so we don't have to worry about finding a parking space or walking from the parking lot to the destination. In the USA sometimes if you go to a large church, you have to allow the time to get from the parking lot to the building.
Yesterday we didn't have to plan on allowing time to get from the parking lot rather we needed to allow time to get from the first floor to the 18th floor where our service was. When you have a few thousand people gathering in the building at the same time for various services it can take time. I will say it is organized the elevators are marked with which floors they will go to and you get in line for the floor that you want. We made it but a bit late.
