Shared expenses. In a typical vanpool, seven to fifteen commuters ride together, each contributing a low monthly fare that gets them a comfortable van, and covers all maintenance and repairs, and all insurance, too.
Not only is the cost of gas spread out among all the riders, each saves on the wear and tear on their car. You car won’t depreciate as fast, nor need maintenance as often. For some people, a vanpool means not having to buy a new or used car just to be sure of having a vehicle they can rely on to make a daily long-distance commute.
