Don't be silly. You're comparing apples and oranges. Do you really think that group of vehicles is going to be controllable in a panic, or emergency situation? Like if he had to swerve to avoid something in the highway or stop very quickly. Be reasonable, some regulations are there for a reason.
And I agree with you on some points: driver's license examinations should be tougher from day one. And yes, some people have no business driving a big fifth wheel or coach. But that does not negate the fact that some things are flat out unsafe.
One of the reasons for speed limits is revenue generation and the other is an advisory of what a safe speed is for the area. And yes, you're absolutely right: "We should just be able to run as fast as we want as long as it's safe right?" that's exactly right. "As long as it's safe"!!
