In the beginning, everyone walked about on foot. People liked it; most stuff you needed was close enough, and if it occasionally rained on you, well, you needed to sleep more often, so what if you can't do everything all of the time.
Someone invented the train and it was well regarded; now even common people could travel far.
Then one day some reckless person thought of putting a train engine on a waggon and getting around without horses or tracks. It didn't appeal to most people; it was too expensive and didn't solve any real problems most people had. Plus it was dangerous and killed people. Some even more reckless person developed a way to make them cheap enough lots of people could afford them, but they were still dangerous and didn't really solve any real problem, so only avant gard people bothered to buy them.

So the most dangerous group of people—marketeerscame up with an evil plan to take over the world. They'd convince everyone that people who walked across streets without looking were backwards, and they'd mock memorials of children who idiot car drivers killed. They'd also make them a status symbol; girls wouldn't go for guys who walked, they were far too pedestrian!
Eventually the world became a completely different place because these people convinced us we wanted something that wasn't helpful—in fact, nowadays it takes people longer to get places with cars than it took to get there before cars—and kills people both directly (through, ahem, direct hits), indirectly (via side-swipes), via the pollution that the poor sods breathe in, and probably through climatatological effects.
