Depends on the car and you should fill to the correct PSI level if you do not have a totally empty system.
The amount of time that people keep their car varies greatly. Some people buy a car and keep it until it is no longer running. Other buy a new car each year.
Let's say the car cost $3,000. Cans are about ten cents each. It would take you 30,000 cans.
There are many items that should be included in a car emergency kit. Maps, rags, flashlight with batteries, flares, empty gas cans, a jack, shovel and a pocket knife to name a few things.
Non smokers keep objects such as gum and candy in car ashtrays. An empty car ashtray could also potentially be used to store currency if hidden away from prying eyes.
Some people might open the windows a little bit to let air in when it's very hot out, but most shut their windows tight to try and keep thieves out.
