|Automobiles are a common sight for more than a century. Initially for the rich and affordable, now they are indispensible transport equipment, although some builds remain as luxury goods for the most affluent. Compared with other products and equipment which have gone through radical and disruptive changes, an automobile is still very much the same vehicle for the last 50 years, although there has been much better control, electronics, safety, fuel economy, comfort and various other factors. Recently, hybrid and electric automobiles are beginning to enter the consumer market. Wide-spread acceptance by users is yet to be fully established as the necessary infrastructure must be in place to allow pervasive use in the cities and outskirts.
