I am seriously considering taking a picture of my car right now and showing what a HORRIBLE example I am setting. This is one that I really need to adhere to, but I don’t know that I ever will.
Messy cars make you less likely to be able to transport your friends and family in an emergency. Look at your car and ask yourself: can every member of my household fit themselves and maybe one emergency bag in this? If the answer is no, then you are not ready for an emergency.
If you have to pause to take 5 to 10 minutes to sweep a bunch of crap out of your car, then that tornado has caught your messy self. The zombies will be chewing on you pretty fast as well.
While you may think that you will have time to empty the junk from your trunk (ha!), especially if you have help, those are still minutes wasted that you could be using to run the heck away.
Clean your car and then see if you have everything necessary for a survival situation neatly packed in a bag in the trunk.
This should give you a minor edge in a zombie apocalypse situation, as well as making your car less disgusting for a friend or prospective hottie to want to get into.
