We're all familiar with daily car rental. Even hourly car rental is becoming a growing trend, with car-sharing services allowing you to pick up a car somewhere in a city and deposit it somewhere else, paying for the hours in between.

In Europe, things are taken one step further, with rental by the minute.

Popular Daimler-owned car-sharing service Car2Go is flooding the streets of Berlin, Germany, with Smart ForTwos as part of its by-the-minute rental service, attracting those who might not need--or be able to afford--a car. For many, the concept of not owning a car but being able to use one when required makes a lot of sense.

While the fleet of distinctive blue and white Smarts partly takes aim at BMW, whose DriveNow rental fleet is now half that of Car2Go's 1,000-strong ForTwo fleet, it's also a burgeoning business, reports Bloomberg.

Car-sharing membership in Europe is expected to rise from 700,000 at the end of last year, to a staggering 15 million by 2020. As the cost of driving rises, many are discovering that they can do without owning a car altogether

City centers in Europe are becoming increasingly car-unfriendly, with traffic, road-charging schemes and restrictions. Throw in a wealth of excellent public transport options in the average European city, and the appeal of car ownership is waning for city-dwellers.

For making short trips, like a commute to work, the benefits of car-sharing are clear. Both Daimler's Car2Go and BMW's DriveNow services charge an identical 29 cents per minute in Berlin, making short drives quite cost-effective--particularly since there's no worries over paying for parking or gasoline.

The services also have an ulterior motive. With car ownership among younger drivers expected to dwindle over the coming decades, short-term rentals are vital to carmakers for getting people behind the wheel of their products. Automakers can make money in the short term via the rentals, but also encourage users to stick with the brand if they decide to buy their own car.

While the U.S. market is still very different to that of Europe, car-sharing is still growing in popularity, with Car2Go now operating in several cities (with some even going electric), and other firms like Zipcar also making car-sharing incredibly easy.
