The mass transportation, the situation, the traffic rule, the situation,

[Rachel Adams]

Are the words in brackets also possible or should I remove them?

"For people, it's more convenient to use (the) car/their cars than (the) mass transportation systems. People pay no attention to (the) demand pressures. I don't think I will violate (the) (any) traffic rules. But my friend says it depends on (the)/a situation. I don't agree. I don't break (any) (the) traffic rules. If did, I would ask what rule I broke and pay (for) traffic ticket. I prefer to use (the) subway. If I am in a hurry and if (the) mass transport isn't working, I take a taxi. If (the) subway station is too far, I take a taxi."

Context for "demand pressures". "The government isn't facilitating the traffic flow. In addition, as more and more "demand pressure" is put on gasoline supplies, and as more taxes are added by the government to regulate usage, prices are rising dramatically."

"For people, it's more convenient to use (the) car/their cars

Use the car or their cars; car doesn't work.

than (the) mass transportation systems.

Unless you're referring to particular mass transportation systems, omit "the".

People pay no attention to (the) demand pressures.

Unless you're referring to particular demand pressures, omit "the".

I don't think I will violate (the) (any) traffic rules.

Unless you're referring to particular traffic rules, omit "the"; "any" adds emphasis.

But my friend says it depends on (the)/a situation.

You need "the"; "a" is wrong.

I don't break (any) (the) traffic rules.

That's a repeat.

If did, I would ask what rule I broke and pay (for) traffic ticket.

No. You're not buying the ticket! Say "I would pay the fine".

I prefer to use (the) subway.

"The" is required.

If I am in a hurry and if (the) mass transport isn't working, I take a taxi.

The underlined part is unnatural. Omit "the" and say, for example, "if public transport isn't available/an option".

If (the) subway station is too far, I take a taxi."

"The" is required.
