What this means is that most of the time there is only one person, and the next most common number is two. Very rarely are there three or more people in a vehicle. Of course, increasing the size of vehicles would be convenient in some cases. However, increasing the number of seats in a vehicle would make riding about 20% more expensive per seat.
