What is the ruling on drawing cars as they appear in reality for enjoyment, and is that considered a theft of the owners' rights?

It appears from the questioner's query and previous questions that he suffers from excessive waswasa (whispers/obsessive thoughts). The cure for this is to completely disregard these waswasa, to stop engaging with them, to cease following their train of thought, to refrain from asking about them, and to supplicate to Allah for relief from them. There is no issue with drawing cars merely for entertainment; it is not considered an infringement on the intellectual property rights of those cars.
