If it is, then I am guilty.

I think "reckless" is determined by the pilot's/operator's skill level, experience, and knowledge and whether those are in alignment with where he or she has chosen to fly.
If you are a new pilot with a few flights around your yard and a full battery in the neighborhood park as your experience - it is reckless to go film your child's field sport from above. If you have a lot of experience, can quickly regain orientation, are familiar with your equipment's limitations, etc., then go for it from a safe perspective/angle.
If you aren't knowledgeable about radio signals and your drones limitations, it is reckless to fly around the Big Wheel not realizing you will lose signal on the other side, causing RTH to initiate, which in turn makes you bang into the ride then fall through a resin table.

If you fly above traffic, either against or with the flow (as opposed to crossing over traffic) in a manner that makes you a distraction to the drivers below, that is reckless.
But, No, not every flight above a crowd, building, or cars is dangerous or reckless.
These drones are amazingly reliable and safe for 99.9% of the users. It is a small percentage of the users who are not reliable or safe yet.
