Yes, the implication that speed record guys don't carefully plan the aerodynamics is ridiculous and insulting. Might have been true about a few of them who had no real competition.
Another good one to watch is the HPV (human powered) races. They show how important good aero is at relatively low speeds.
And yes, any racing series where top speed is important doesn't have exposed roll bars, or exposed cockpits.
I have noticed the last few years that the auto designers seem to be pointing the sides and headlight areas to direct a lot more air to the sides. The overhead view is also very important. That Mercedes fish car has a quite V shaped nose.
