I think most people go about the initial outbreak in the completely wrong way.
For example. You all want to be with your families and loved ones. You all want food and water and shelter and medical provisions and guns and ammunition and cars and weapons. You can't just go about collecting stuff and finding people and driving about from place to place gathering your supplies in the hope that you'll be able to get a good enough place to lay low with a big enough supply of necessities all while the worlds turned into a living hell. It simply just wouldn't be that simple.
Think about it, you're in work - and all of your stuff is at home. Infection begins.
Just like you, everyone around you wants to find their loved ones and make it back home. How? In the panic, telephone signal out, communication becomes nearly impossible and obviously the people you're looking for would have had the same idea. Try looking. But then where do you find them amidst the chaos?
You get to you car, great. But you need food and water, where you do go? The supermarket? No way. In the time it's taken you to reach your car, make your way safely to the supermarket and avoid becoming infected, how many people had the same idea? How many people tried going to the supermarket, only to find that it's completely empty, looted to the very last bag of sugar - or, full of people who are infected. Supermarkets are busy places, in the sheer volume of people there, at least someone would have turned. Then everyone else gets it.
Guns. How many people do you think leave guns lying around, for the passer by to pick up and use for themselves. Unless the owner of the gun has died and dropped it, you would either need to have had your own guns in the first place, (and hope that no one's nicked them all from your place), or be in a position of work where guns are easy access. For example, the police, or the armed forces. It's not like a game where you can simply wander in to a house and find stock piles of things to use and get away with it all unscathed.
If a zombie apocalypse had broken out, the first thing on my priority list would be to not get eaten. Above all else, survive the Outbreak. Then the real struggle begins.
