Many people don't go very far daily or even weekly. Running to a few stores around town could quickly be done on a cargo bike. Why keep pumping money into an expensive car to go to grocery stores? How much money would you save by significantly reducing the number of times you fill up your car with gas? When you use a car, maintenance can be a real problem. Riding a cargo bike is fun and saves money: that's a win/win situation.
Do you hate wasting time and energy finding a convenient and legal parking spot? What would you pay not to have to go through that problem? Cargo bikes can be chained up almost anywhere, which means they stay safe, and you don't have to worry about parking. It saves much time to park directly in front of the place you need to be.

There are many logical and practical reasons individuals and businesses invest in themselves and cargo bikes. What's your reasoning going to be?
