Actually it should look like this (cars, airplanes, trains, etc.). But if the sentence ends with an abbreviation, the single period will serve to end the sentence, as in cars, airplanes, trains, etc. You do not use double periods. You can, however, use a question mark or exclamation point after a period that ends a sentence. Were you talking about cars, airplanes, trains, etc.? If this looks unusual, it is because abbreviations, such as etc., are generally avoided at the ends of sentences.
You put a period at the end of the sentence to indicate that the sentence has ended.

In a sentence, parenthesis (also known as "brackets") are used to include one thought (or more) inside another thought without interrupting the flow or direction of the thought.

No, you do not need to add an additional period if "etc." is within parentheses at the end of a sentence. The period that ends the abbreviation "etc." also serves as the sentence-ending punctuation.
The period typically goes after the closing parenthesis in American English.
The period goes after the closing parenthesis of the citation.
Right before the quote ends. For example:He said, "You are a jerk."
