Of course not. Lacquer is a different paint altogether. Anything that didn't stick as you were wetting out dried enough within a few feet in the air being atomized as it was. It was a fine mist. Enamels are heavier, don't atomize quite the same (especially with a true HVLP) and act differently during the flow out. That same action allowing the paint to level out is the same that keeps the overspray sticky (for lack of a better word).
I can't imagine what you expected painting a car in the middle of a room if you didn't expect paint everywhere within a certain distance. The floor being the closest and with gravity, it's sure to get a lot of paint. I know this from experience.
What might even seem worse is to cover the area beneath the car 10 feet in each direction only to pull up the coverings and see a huge rectangle in the middle of the floor. I know this too from experience.
Spray painting is a bloody mess. When you want to paint everything in sight like the interior of a home, it's the way to go once the areas not to be painted are covered or masked. Outside it's anyone's guess until you're done and find out how many cars you've gotten overspray on. I know that's a different ball game but when I was painting exteriors for a living, I put the spray gun away by 10 am.
Spray painting equipment manufacturers have been working this problem since the spray gun was invented. They've come a loooong way, but the result has been limited to more paint transferred to the intended surface and less waste. That's about the size of it.
