It has gotten better in 20 years (that's way too long to retain judgement on transportation). Not a ton better, but since most of these companies aren't moving to Dallas proper, it's moot anyways.

How did they remove the cars from the road?

I'd imagine traffic at the mixmaster and various loops are still terrible.

I had a reverse commute (Lower McKinney to Las Colinas), and I'd see gridlock the entire way there (other direction).
