Replying to I'm a Way Better Driver Than You

Does anyone else get pissed when people say that? I'm 16 so I'm just at the age where people are starting to get their licenses, and people say that with a straight face all the time... Like really? I live in a town where traffic is very minimal, and highway driving is the easiest shit ever, so I don't understand what people are basing their driving abilities off of... I mean, you can definitely be a shitty driver, but as long as you're a competent driver, there really isn't much room to be "better" than someone else... And often, people who say they're great drivers fucking blow dick. So what gives?
