If you have kids, don't buy them a car, school bus is safe enough.
If you have wife working, send & pick them up, 1 car is enough.
If you area has a good coverage of public transport, use them.
If you hate the hot wheather in the next few year, reduce your car usage.

The increasing of car lead to the increase of poisonous gas, tar road, oil mining, smoky factory.
Ride a car won't be so cool if we look from the different side.

Utilize your public transport. Kinarut putatan Jalan taruss~
