Back in 2011, I had a two week trip to Taiwan planned for work. I left my car in the long term airport parking lot as I traveled across the globe. The two weeks passed and work needed to extend my stay to ensure the program's success. I thought, "I can't say no, they need me". The last thing on my mind was my car sitting there at the time. Two months later and 30 hours of traveling I land back in Logan airport ready to head home. It took a little searching in the parking garage to remember where my car was but there it was... three of my four wheels flat to the rim. Then when I started the car the engine was misfiring.
Luckily, letting the engine run for 15 minutes actually cleared up whatever caused the misfiring. Once AAA arrived to fill the tires I was ready to go again. I called my Dad to let him know I arrived and told him about the car. He replied as though I should have known, "Of course you had car issues, its just been sitting there. Cars need to move!"
It doesn't have to be a two hour road trip either, a quick trip to the grocery store is all the car needs most days. It's a mechanical system built to move, don't wait until it's too late.
Read previous thought - I don't have time to roll out...
