How can this be legal?

Which is why D.C. is going hardcore strict on speeders doing over 80 MPH on interstates because speeding tickets alone are not stopping drivers from doing it and riding peoples rear bumper when they can't. When one deterrent isn't working, you up the punishment until it does.

And I can honestly say that 80 MPH is about the fastest I've ever felt the need to drive and I don't even like going that fast. Saving an extra minute or two on my ride has never seemed worth it to me.

That's not what it says. Virginia is the one that defines over 80 as reckless per se. But in VA, reckless is a lesser offense than in DC, which has a higher standard but also has harsher penalties when that standard is met.

The problem is the reciprocality. DC is considering the VA reckless offense to be the same as a DC reckless offense - and suspending the license. But they aren't the same offense.

(Its almost impossible to do 84 on the interstate in DC. There's very little interstate in DC anyway).
