When my kids were younger we use to make drives funnier by doing random antics, some of our favorites were – yelling out the windows announcing the street vender’s foods, taunting couples to kiss as they crossed the street, or singing loudly to the music. It’s fun when you can get them to join in your insanity, better when they start to create their own.
One time we decided to involve the parked cars at the stop light. We we would stop we would take turns discovering some random object in the sky and see how many other outside passengers we could get to look before the light turn green. We got quite good at this and on one occasion actually got someone out of the car to look. lol
