ChapterTwoLifestyle factor influences travelbehaviorWhether do different countries tourists' different lifestyle which can influence their travel consumption behaviors? Even, which countries that they will choose to go to travel. For example, when one tourist who owns himself/herself often to drive to go to anywhere habitually. The tourist's driving car habital behavior which will influence that he /she will feel need to rent car to travel to anywhere habitually, when he/she selects to go to the country to travel. Hence, if he/she feels the tourism destination has no any rent car service providers to provide him/her to rent any car to travel anywhere in the country's travel destination. Does the country lack rent car service factor which will influence that he/she will still choose to go to the country to travel in preference? For example, when one New Zealander's family who own at least one car at home. So, the New Zealand whole family every member can often drive car to go to anywhere, even, one family member had driven one car to leave his/her home. So, driving own car activity or behavior has been one habitual activity to influence the New Zealand every member to feel the travelling destination needs have rent car service provider supplies cars to let them to rent to travel. The driving car lifestyle has caused the whole New Zealander family driving habit. When the family's sons) and/or daughter(s) need(s) to go to school or go to shopping as well as their parents also need to drive their cars to go to office to work in themselves home town often. In common, there are many New Zealanders who will have at least one car at home because they feel that they can drive their themselves cars to go to anywhere in New Zealand more than waiting bus or tram or train or ferry etc. public transportation tools more conveniently. So, New Zealanders' driving own car habit will influence their lifestyle to feel that they also need to rent cars to travel to go to any where to travel to replace to wait public transportation tools choice in the travelling destination during their journey.For shopping trips is more influenced by their driving car activities. So, it seems that this New Zealander families will be influenced to their tourism destination need, they need the tourism destination has car renting service provider to be supplied anywhere to let them can drive the renting cars to go to anywhere in tourism destination. It means that when the tourim destination has less rent car providers can provide renting car services to drive anywhere or it has none any renting car service providers are existing in the tourism destination. Then, the renting car service providers number shortage or none any renting car service providers to be provided to the country's tourism destination, which will cause the New Zealander families do not perfer to choose to go to the country to travel generally, e.g. Hong Kong, China, Korea these Asia countries have no many rent car service providers in these countries. So, the New Zealand families won't prefer to choose to go these countries to travel when they discover these Asia countries lack enough rent car service providers to let them to drive to travel in themselves conveniently. Otherwise, America, England, Japan etc. countries have many rent car service providers. So, these countries will be this New Zealander families' preferable tourism countries. Thus, the New Zealand families' driving ownership car lifestyle will influence their travel behaviors to choose to go to the country which can have many rent car providers in the tourism country any where tourism destinations in preference.
