In our lifetimes, the age of the human driver will start to come to a close. Sure, for now, self-driving cars can't tell the difference between mowing down an old lady and hitting a fire hydrant, but they're on a steep learning curve and they're coming of age rapidly. At some point in the next 20 years, they will be better drivers than the vast majority of people. While the law may drag its feet and insist the human driver retains at least the option of control, eventually the insurance companies will step in and simply state that they're not going to cover you behind the wheel, or they'll make it conditional on you being well-rested, breathalyzed, and with absolutely no distractions present like music, a phone, or kids. Thus it's quite likely that a baby born today will never learn to drive.

Until then, of course, we're stuck with all the drivers who make the whole task so unpleasant. As Jean-Paul Sartre wisely put it, "Hell is other people," and in no field of human endeavor is this truer than it is when it comes to driving. Still, picking WHICH other people are the most ghastly is still instructive - and a lot of fun. Who do you hate most on the roads? Let's find out!
