car-full

A lot of the times when I'm on the bus and it's stuck in a jam, the scene outside is a bit annoying: 90% of the cars have like 1 out of 5 seats occupied, some 1 out of 7, and the occasional mammoth excursion bus with only the driver and zero passenger inside. Don't believe? Look at the picture to the left, the car only has one head inside while the bus is packed. (I didn't photoshop away any head)

If we use superposition theorem, with the road space occupied by one car with 1 person inside, we can easily have luxuriously 4 rows of 4 =16 people on part of a bus taking up the same road area. And, if it is a double decker, 16 x 2 = 32. Then plus some fella standing, 32 + 8 = 40. Isn't it wonderful how many people can be transported taking up the same road space as a car with ONE person? Don't believe? Look at the picture again, see how many green heads and how many red head? Then we integrate it with respect to the bus's length and blah blah blah...

I just find it lame that people buy cars with 5 seats when most of the time they only use that one seat with the steering wheel.

P/S. It is not only traffic congestion, but also environment. A double-decker bus uses one engine to ferry 120+ passenger (a double decker Olympian is licensed to carry 131); a car uses one engine to ferry 1 person. Imagine 120 people driving 120 cars, lotsa fossil fuel is wasted and lotsa engine exhaust...
