 Pro Street cars should appear to be more at home on the drag strip than the street, while remaining street legal and not gutted like a Race Car or Bracket Race car.
 Typically called a Backhalf car (tubbed).

The Crystal Street Historic District is a group of three triple deckers at 30-34 Crystal Street, facing University Park in the Main South area of Worcester, Massachusetts.
 The houses appear to have been built for developer James Harrop, who lived at 30 Crystal Street and owned them for 35 years.
 At the time of there construction c. 1892, Harrop is described in city directories as a wool sorter, but over the following years he eventually became a real estate developer.
 The houses were built at a time when the area was experiencing significant development due to the extensions of the electrified street cars to the area.
The Silver State Classic Challenge, called the fastest road race in the world by Guinness, is an authorized Open Road Racing event that is run on a 90 mi stretch of State Route 318 in Nevada, which is closed for the occasion.
 The event has been run since 1988, and was the venue for the highest speed achieved on a public highway, when Charles "Chuck" Shafer and Gary Bockman averaged 207.7801 mi/h in May 2000, in a Chrysler LeBaron ARCA race car.
 Although high-speed race cars receive much of the publicity, the majority of participants take part in mainstream street cars at average speeds ranging from 95 to .
 These cars run the gamut from sports cars such as Corvettes and Mustangs to sedans such as Nissan Skylines, Mercedes wagons, and even Saturns.
Pro Stock is a class of drag racing featuring "factory hot rods".
 The class is often described as "all motor", due to the cars not using any form of forced induction such as turbocharging or supercharging, or other enhancements, like nitrous oxide, along with regulations governing the modifications allowed to the engines and the types of bodies used.
The Geary Street, Park and Ocean Railway was one of the first cable car operators in San Francisco.
 Operation commenced in 1880, and the route soon proved quite popular.
 The line was purchased by the Market Street Railway in 1887.
 In 1912, the city declined to renew the franchise and instead took over operation of the Geary Street railway.
 The line was converted into an electric streetcar line, forming the first element of the San Francisco Municipal Railway (Muni) that was to come to be synonymous with transit in that city.
 Muni replaced the street cars with motor coaches in 1956.
 Today, the bus routes that serve the Geary corridor are the most heavily used in San Francisco.
An open-wheel car (formula car, or often single-seater car in British English) is a car with the wheels outside the car's main body, and usually having only one seat.
 Open-wheel cars contrast with street cars, sports cars, stock cars, and touring cars, which have their wheels below the body or inside fenders.
 Open-wheel cars are usually built specifically for racing, frequently with a higher degree of technological sophistication than in other forms of motor sport.
 Open-wheel street cars, such as the Ariel Atom, are very scarce as they are often impractical for everyday use.
The Hedley Hi-V, a New York City Subway car, was built between 1910 and 1911, which were motor cars and then in 1915 an order for trailers that were numbered 4223-4514.
 All were built by the Standard Steel Car Company, Pressed Steel Car Company, and Pullman Company.
 These were the first cars built with center doors.
 They were also the last high voltage cars built for the system as all subway cars delivered afterward had low voltage since high voltage cars were a hazard to both the train operators and track crews, which is probably one of a few reasons why the TA was in a rush to get rid of these cars by the mid 1950s with the R17, R21, and R22 cars.
The Red Car Trolley is a tramway and transportation attraction at Disney California Adventure at the Disneyland Resort in Anaheim, California.
 Construction began on January 4, 2010 and the attraction opened on June 15, 2012 as part of the re-dedication of the park.
 The attraction features replicas of the Pacific Electric Railway's "Red Cars" that once traversed much of Southern California, and provides transportation between the park's main entry at Buena Vista Street and in Hollywood Land.
 Built by Brookville Equipment of Brookville, Pennsylvania, these cars are replicas of the Pacific Electric "Hollywood" class cars, built by St. Louis Car in the 1920s.
 Brookville is a builder of diesel switcher locomotives and a rebuilder of classic trolley cars.
 Unlike the original Pacific Electric trolley cars, which drew their power from an overhead wire, the "Red Car Trolley" cars are battery operated with nonoperative overhead wires presented for authentic show.
 The cars operate completely cordless through onboard batteries using inductive charging.
 The batteries are periodically charged through non-contact charging using induction coils in the ground where the cars rest at Sunset Boulevard stop.
Trans-Am production cars were factory-built pony cars based on vehicles raced in the Sports Car Club of America Trans-Am Series.
 These cars were used largely for homologation purposes, but also as promotional tools for the series.
 The first Trans-Am street car was Chevrolet's Z/28 Camaro, which entered production in 1967.
 By 1970 six makes were producing street cars based on their racing vehicles.
 Due to their low production numbers and high performance, these vehicles are highly collectible today.
