It's not just overconfidence, it's selfishness.

Speeding feels like "I'm more important than everyone else and the safety of others and rules don't apply to me" personally. It's one thing to match the speed of traffic and avoid being a nuisance (that I'm fine with) - a lot of people just think they're the main character and everyone else is just in their way.

It's a problem that goes way beyond driving, sadly.
