Question: What had the people whose cars became more highly sought after as they were more fuel efficient failed to capture?

full_context: Document 1: Automotive industry: Around the world, there were about 806 million cars and light trucks on the road in 2007, consuming over 980 billion litres (980,000,000 m3) of gasoline and diesel fuel yearly. The automobile is a primary mode of transportation for many developed economies. The Detroit branch of Boston Consulting Group predicted that, by 2014, one-third of world demand would be in the four BRIC markets (Brazil, Russia, India and China). Meanwhile, in the developed countries, the automotive industry has slowed down. It is also expected that this trend will continue, especially as the younger generations of people (in highly urbanized countries) no longer want to own a car anymore, and prefer other modes of transport. Other potentially powerful automotive markets are Iran and Indonesia.
Document 2: Pacific War: Two battle-hardened Australian divisions were steaming from the Mid-East for Singapore. Churchill wanted them diverted to Burma, but Curtin insisted on a return to Australia. In early 1942 elements of the Imperial Japanese Navy proposed an invasion of Australia. The Japanese Army opposed the plan and it was rejected in favour of a policy of isolating Australia from the United States via blockade by advancing through the South Pacific. The Japanese decided upon a seaborne invasion of Port Moresby, capital of the Australian Territory of Papua which would put Northern Australia within range of Japanese bomber aircraft.
Document 3: 1973 oil crisis: The crisis reduced the demand for large cars. Japanese imports, primarily the Toyota Corona, the Toyota Corolla, the Datsun B210, the Datsun 510, the Honda Civic, the Mitsubishi Galant (a captive import from Chrysler sold as the Dodge Colt), the Subaru DL, and later the Honda Accord all had four cylinder engines that were more fuel efficient than the typical American V8 and six cylinder engines. Japanese imports became mass-market leaders with unibody construction and front-wheel drive, which became de facto standards.
Document 4: 1973 oil crisis: Despite being relatively unaffected by the embargo, the UK nonetheless faced an oil crisis of its own - a series of strikes by coal miners and railroad workers over the winter of 1973–74 became a major factor in the change of government. Heath asked the British to heat only one room in their houses over the winter. The UK, Germany, Italy, Switzerland and Norway banned flying, driving and boating on Sundays. Sweden rationed gasoline and heating oil. The Netherlands imposed prison sentences for those who used more than their ration of electricity.
Document 5: Pacific War: The war entered a new phase with the unprecedented defeat of the Japanese at Battle of Suixian-Zaoyang and 1st Battle of Changsha. After these victories, Chinese nationalist forces launched a large-scale counter-offensive in early 1940; however, due to its low military-industrial capacity, it was repulsed by Japanese army in late March 1940. In August of 1940, Chinese communists launched an offensive in Central China; in retaliation, Japan instituted the "Three Alls Policy" ("Kill all, Burn all, Loot all") in occupied areas to reduce human and material resources for the communists. By 1941 the conflict had become a stalemate. Although Japan had occupied much of northern, central, and coastal China, the Nationalist Government had retreated to the interior with a provisional capital set up at Chungking while the Chinese communists remained in control of base areas in Shaanxi. In addition, Japanese control of northern and central China was somewhat tenuous, in that Japan was usually able to control railroads and the major cities ("points and lines"), but did not have a major military or administrative presence in the vast Chinese countryside. The Japanese found its aggression against the retreating and regrouping Chinese army was stalled by the mountainous terrain in southwestern China while the Communists organised widespread guerrilla and saboteur activities in northern and eastern China behind the Japanese front line.
Document 6: Pacific War: As many Japanese had feared, Japan's supply arrangements could not maintain her forces. Once Mutaguchi's hopes for an early victory were thwarted, his troops, particularly those at Kohima, starved. During May, while Mutaguchi continued to order attacks, the Allies advanced southwards from Kohima and northwards from Imphal. The two Allied attacks met on 22 June, breaking the Japanese siege of Imphal. The Japanese finally broke off the operation on 3 July. They had lost over 50,000 troops, mainly to starvation and disease. This represented the worst defeat suffered by the Japanese Army to that date.[citation needed]
Document 7: Pacific War: In January, Japan invaded Burma, the Dutch East Indies, New Guinea, the Solomon Islands and captured Manila, Kuala Lumpur and Rabaul. After being driven out of Malaya, Allied forces in Singapore attempted to resist the Japanese during the Battle of Singapore but surrendered to the Japanese on 15 February 1942; about 130,000 Indian, British, Australian and Dutch personnel became prisoners of war. The pace of conquest was rapid: Bali and Timor also fell in February. The rapid collapse of Allied resistance had left the "ABDA area" split in two. Wavell resigned from ABDACOM on 25 February, handing control of the ABDA Area to local commanders and returning to the post of Commander-in-Chief, India.
Document 8: Guadalcanal campaign: In order to exploit the victory in the Battle for Henderson Field, Vandegrift sent six Marine battalions, later joined by one U.S. Army battalion, on an offensive west of the Matanikau. The operation was commanded by Merritt Edson and its goal was to capture Kokumbona, headquarters of the 17th Army, west of Point Cruz. Defending the Point Cruz area were Japanese army troops from the 4th Infantry Regiment commanded by Nomasu Nakaguma. The 4th Infantry was severely understrength because of battle damage, tropical disease, and malnutrition.
Document 9: Pacific War: The battle of Iwo Jima ("Operation Detachment") in February 1945 was one of the bloodiest battles fought by the Americans in the Pacific War. Iwo Jima was an 8 sq mile (21 km2) island situated halfway between Tokyo and the Mariana Islands. Holland Smith, the commander of the invasion force, aimed to capture the island, and utilize its three airfields as bases to carry out air attacks against the Home Islands. Lt. General Tadamichi Kuribayashi, the commander of the island's defense, knew that he could not win the battle, but he hoped to make the Americans suffer far more than they could endure.
Document 10: Pacific War: The Japanese responded to the Allied attacks by launching an offensive of their own into India in the middle of March, across the mountainous and densely forested frontier. This attack, codenamed Operation U-Go, was advocated by Lieutenant General Renya Mutaguchi, the recently promoted commander of the Japanese Fifteenth Army; Imperial General Headquarters permitted it to proceed, despite misgivings at several intervening headquarters. Although several units of the British Fourteenth Army had to fight their way out of encirclement, by early April they had concentrated around Imphal in Manipur state. A Japanese division which had advanced to Kohima in Nagaland cut the main road to Imphal, but failed to capture the whole of the defences at Kohima. During April, the Japanese attacks against Imphal failed, while fresh Allied formations drove the Japanese from the positions they had captured at Kohima.
Document 11: 1973 oil crisis: In 1973, Nixon named William E. Simon as the first Administrator of the Federal Energy Office, a short-term organization created to coordinate the response to the embargo. Simon allocated states the same amount of domestic oil for 1974 that each had consumed in 1972, which worked for states whose populations were not increasing. In other states, lines at gasoline stations were common. The American Automobile Association reported that in the last week of February 1974, 20% of American gasoline stations had no fuel.
Document 12: 1973 oil crisis: The crisis had a major impact on international relations and created a rift within NATO. Some European nations and Japan sought to disassociate themselves from United States foreign policy in the Middle East to avoid being targeted by the boycott. Arab oil producers linked any future policy changes to peace between the belligerents. To address this, the Nixon Administration began multilateral negotiations with the combatants. They arranged for Israel to pull back from the Sinai Peninsula and the Golan Heights. By January 18, 1974, US Secretary of State Henry Kissinger had negotiated an Israeli troop withdrawal from parts of the Sinai Peninsula. The promise of a negotiated settlement between Israel and Syria was enough to convince Arab oil producers to lift the embargo in March 1974.
Document 13: 1973 oil crisis: Compact trucks were introduced, such as the Toyota Hilux and the Datsun Truck, followed by the Mazda Truck (sold as the Ford Courier), and the Isuzu-built Chevrolet LUV. Mitsubishi rebranded its Forte as the Dodge D-50 a few years after the oil crisis. Mazda, Mitsubishi and Isuzu had joint partnerships with Ford, Chrysler, and GM, respectively. Later the American makers introduced their domestic replacements (Ford Ranger, Dodge Dakota and the Chevrolet S10/GMC S-15), ending their captive import policy.
Document 14: 1973 oil crisis: OPEC soon lost its preeminent position, and in 1981, its production was surpassed by that of other countries. Additionally, its own member nations were divided. Saudi Arabia, trying to recover market share, increased production, pushing prices down, shrinking or eliminating profits for high-cost producers. The world price, which had peaked during the 1979 energy crisis at nearly $40 per barrel, decreased during the 1980s to less than $10 per barrel. Adjusted for inflation, oil briefly fell back to pre-1973 levels. This "sale" price was a windfall for oil-importing nations, both developing and developed.
Document 15: Solar energy: The 1973 oil embargo and 1979 energy crisis caused a reorganization of energy policies around the world and brought renewed attention to developing solar technologies. Deployment strategies focused on incentive programs such as the Federal Photovoltaic Utilization Program in the US and the Sunshine Program in Japan. Other efforts included the formation of research facilities in the US (SERI, now NREL), Japan (NEDO), and Germany (Fraunhofer Institute for Solar Energy Systems ISE).
