Public transport can also reduce traffic jams and free up road
space...
Imagine the space occupied by a bus carrying 100 passengers, and
the space occupied by 100 cars with 1 driver... (Even if 4 people
share 1 car, it will take 25 cars to transport 100 people.)
This is one reason why I prefer public transport. I don't wanna
contribute to traffic congestions and global warming. Another
reason is that I wanna save money... Public transport may be
getting more and more expensive, but I feel that having a car is
even much much more expensive. (To me, a car is a big liability,
since it depreciates quickly.)
