[Q]: Motorized bicycle -- The legal status of an ICE motorized bicycle in the United States is presently determined by the laws of each state and/or local jurisdiction. Several states allow ICE motorbikes to be operated on roadways without registration, tax, or licensing in the same manner as bicycles, providing certain restrictions are observed. Many state jurisdictions use limits on top speed and/or engine displacement to determine if ICE motorized bicycles require registration and licensing--sometimes as mopeds, sometimes as motorcycles. Some states prohibit the use of motorbikes on multi-use recreational paths or high-speed, limited access roadways, while others require additional safety equipment for operation on public roads, such as wearing a helmet. Many United States cities and other local jurisdictions may impose additional restrictions upon ICE motorized bicycles when operated on public streets and roadways.

[Q]: Doubly linked list -- In computer science, a doubly linked list is a linked data structure that consists of a set of sequentially linked records called nodes. Each node contains two fields, called links, that are references to the previous and to the next node in the sequence of nodes. The beginning and ending nodes' previous and next links, respectively, point to some kind of terminator, typically a sentinel node or null, to facilitate traversal of the list. If there is only one sentinel node, then the list is circularly linked via the sentinel node. It can be conceptualized as two singly linked lists formed from the same data items, but in opposite sequential orders.
[A]: is double link list a linear data structure

[Q]: Opel -- The Opel brand is present in the most of Europe, in parts of North Africa, in South Africa, the Middle East, in Chile and in Singapore. Their models have been rebadged and sold in other countries and continents, such as Vauxhall in Great Britain, Chevrolet in Latin America, Holden in Australia and New Zealand, and previously, Saturn in the United States and Canada. Following the demise of General Motors Corporation's Saturn division in North America, Opel cars are currently rebadged and sold in the United States, Canada, Mexico, and China under the Buick name with models such as the Opel Insignia/Buick Regal, Opel Astra sedan/Buick Verano (both which share underpinnings with the Chevrolet Cruze), and Opel Mokka/Buick Encore.
