An automobile is a vehicle that moves itself rather than being moved by another vehicle or animal. A motor car is usually shortened to just car. A car is a wheeled passenger vehicle that carries its own engine or motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods. An automobile, usually called a car or a truck, is a wheeled vehicle that carries its own engine. Older terms include horseless carriage and motor car. It has seats for the driver and, almost without exception, for at least one passenger. Significant reductions in death and injury have come from the addition of Safety belts and laws in many countries to require vehicle occupants to wear them. Airbags and specialised child restraint systems have improved on that. Structural changes such as side-impact protection bars in the doors and side panels of the car mitigate the effect of impacts to the side of the vehicle. Many cars now include radar or sonar detectors mounted to the rear of the car to warn the driver if he or she is about to reverse into an obstacle or a pedestrian. Some vehicle manufacturers are producing cars with devices that also measure the proximity to obstacles and other vehicles in front of the car and are using these to apply the brakes when a collision is inevitable. There have also been limited efforts to use heads up displays and thermal imaging technologies similar to those used in military aircraft to provide the driver with a better view of the road at night.

Law Firm

A law firm is a business entity formed by one or more lawyers to engage in the practice of law. The primary service rendered by a law firm is to advise client’s individuals or corporations about their legal rights and responsibilities, and to represent clients in civil or criminal cases, business transactions, and other matters in which legal advice and other assistance are sought.

In many countries, including the United States and the United Kingdom, there is a rule that only lawyers may have an ownership interest in, or be managers of, a law firm. Thus, law firms cannot quickly raise capital through initial public offerings on the stock market, like most corporations. In the United States this rule is promulgated by the American Bar Association and is adhered to in all U.S. jurisdictions, except the District of Columbia. The U.K. has a similar rule, but in recent years law firms have been able to take on a limited number of non-lawyer partners.

The rule was created in order to prevent conflicts of interest. In the adversarial system of justice, a lawyer has a duty to be a zealous and loyal advocate on behalf of the client, and also has a duty to not bill the client unreasonably. Also, as an officer of the court, a lawyer has a duty to be honest and to not file frivolous cases or raise frivolous defenses. A lawyer working as a shareholder-employee of a publicly traded law firm would be strongly tempted to evaluate decisions in terms of their effect on the stock price and the shareholders, which would directly conflict with the lawyer's duties to the client and to the courts.

Law firms are typically organized around partners, who are joint owners and business directors of the legal operation; associates, who are employees of the firm with the prospect of becoming partners; and a variety of staff employees, providing paralegal, clerical, and other support services. An associate may have to wait as long as 9 years before the decision is made as to whether the associate "makes partner." Many law firms have an "up or out policy" pioneered around 1900 by partner Paul Cravath of Cravath, Swaine & Moore: associates who do not make partner are required to resign and join another firm, go it alone as a solo practitioner, go to work in-house in a corporate legal department, or change professions burnout rates are very high in law.

Making partner is very prestigious at large or midsized firms, due to the competition that naturally results from higher associate-to-partner ratios. Such firms may take out advertisements in legal newspapers to announce who has made partner. Traditionally, partners shared directly in the profits of the firm, after paying salaried employees, the landlord, and the usual costs of furniture, office supplies, and books for the law library or a database subscription. Partners in a limited liability partnership can largely operate autonomously with regard to cultivating new business and servicing existing clients within their book of business. However, many large law firms have moved to a two-tiered partnership model, with equity and non-equity partners. Equity partners are considered to have ownership stakes in the firm, and share in the profits and losses of the firm. Non-equity partners are generally paid a fixed salary albeit much higher than associates, and they are often granted certain limited voting rights with respect to firm operations. The oldest continuing partnership in the United States is that of Cadwalader, Wickersham & Taft, founded in 1792 in New York City.
