Many people don't understand, it's not about YOU. It's about all the other morons around you. America gives a driver's license to anyone, which means that you're surrounded by idiots that managed to pass an open book test. The consequences of this are obvious, people don't act predictably, don't follow proper driving procedures, and often lack skill. So, you may be overqualified to go 100 MPH in a 60, but the 16 year old girl that just swerved in front of you going 60 while texting her friend is not.

Why do you think Germany's autobahn has a similar death rate to our interstates, despite being unregulated? In europe, driving is not looked upon as a right. It's a responsibility, and passing the test is actually a challenge.

Answering the question, is it more dangerous, hell yes. Like JP said, the difference in speed/closing rate is what kills people. This is beyond the obvious fact that things just happen faster, and when something unpredictable (other drivers) happens, you have less time to react. The implications are obvious. I typically go 10 over on the Interstate, but those that think 100 MPH is safe because they've spent some time on the track are morons.
