In recent years, the discussion on whether cars can enter ordinary Chinese families has not stopped. Some people think that the relaxation of the regulation of private cars can promote the development of China's automobile industry, but at the same time, it will make the originally tense traffic situation worse, thereby affecting economic and social order. Therefore, China's private cars should not develop significantly over the past five years. Which of the following, if true, can best support the above view? ['Transportation will develop with the development of the car industry.', 'Always develop the automobile industry first, then the transportation business.', 'Road conditions in China are unlikely to improve in the near future.', 'Public transportation should be vigorously developed.']
