# Glass Dome Minicars The Four 1 Vehicle is a Green Option for the Single Rider By Katherinev123 | Published 2009-12-30 | Autos Source: Trend Hunter, https://www.trendhunter.com/trends/four-1-vehicle References: [thedesignblog.org](http://www.thedesignblog.org/entry/four1-single-seat-vehicle-ensures-an-eco-office-commute/) & [productdesignforums](http://www.productdesignforums.com/index.php?showtopic=11746) The idea of carpooling is an earth-friendly one but that doesn’t mean people will do it. Designer Car Walster, attempting to combat this problem, has created the ‘Four 1’ vehicle. The Four 1 vehicle is a concept car that aims to eliminate the fuel waste and occupied road space from single riders driving in four-seater cars. With the ability to switch from being a hybrid to a fully electric car, the Four 1 vehicle is a single-seater auto with a glass dome cabin. It is powered by a 500cc motorbike engine that can travel about 40 miles a day and features an adjustable seat, movable steering wheel, and a back window that opens like a hatch back for storing luggage or daily essentials. ## Trend Insights (Trend Hunter) - Score: 2.7/10 - Popularity: 43% | Activity: 31% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Millennial - Top markets: Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Autos](https://www.trendhunter.com/autos) ## Key Themes ### What Makes This Trend Stand Out - **Single-rider Transportation:** Opportunity for designing innovative vehicles that cater to the needs of single riders, reducing fuel waste and occupied road space. - **Hybrid-to-electric Conversion:** Potential for developing cars with the ability to switch between hybrid and fully electric modes, providing flexibility for different driving needs and reducing carbon emissions. - **Customizable Compact Cars:** Possibility for creating compact vehicles with adjustable features and flexible designs to optimize comfort and storage space for single riders. ### Sectors Adopting This - **Automotive Industry:** Disruptive innovation opportunities for car manufacturers and designers to develop eco-friendly, single-rider vehicles with advanced features. - **Green Technology Industry:** Opportunity for green tech companies to explore and improve hybrid-to-electric conversion technology for automobiles, promoting sustainability in transportation. - **Urban Mobility Industry:** Potential for urban mobility companies to design and provide compact, customizable vehicles that cater to the needs of single riders, addressing traffic congestion and environmental concerns. ## Related on Trend Hunter - [Modular One-Person Cars](https://www.trendhunter.com/trends/cmpn-concept.md) - [Hybrid Design Commuter Vehicles](https://www.trendhunter.com/trends/robotic-city-car.md) - [Single-Seater Track Car Concepts](https://www.trendhunter.com/trends/polestar-11.md) - [Electric City-Friendly Microcars](https://www.trendhunter.com/trends/tesla-mini.md) - [Transforming Commuter Vehicles](https://www.trendhunter.com/trends/audi-vista-roadster.md) - [Three-Wheel Pod EVs](https://www.trendhunter.com/trends/the-nimbus-one.md) - [Four-Wheeled Hybrid Bike Designs](https://www.trendhunter.com/trends/karver-cyle-concept-k1.md) - [Streamlined Two-Seater Electric Cars](https://www.trendhunter.com/trends/autonomous-electric-car-concept.md) - [Transparent Self-Driving EVs](https://www.trendhunter.com/trends/unimo-electric-vehicle.md)
