# Retractable Speed Bumps Innovative Design Flattens for Slow Drivers By Cecilia Biemann | Published 2008-12-12 | Autos Source: Trend Hunter, https://www.trendhunter.com/trends/retractable-speed-bumps-flattens-for-slow-drivers References: [yankodesign](http://www.yankodesign.com/2008/12/11/speed-bumps-that-flatten-for-slow-speeds/) Designed by Jae-yun Kim and Jong-Su Lee, this innovative speed bump design flattens out when you cross it at a low speed. The idea is to reward careful, slow drivers who approach the speed bump at speeds below 30km/h by giving them a smooth ride over the speed bump; those who exceed this speed will have to suffer the bump. Finally, an end to spilled drinks and grubby cup holders caused by large unavoidable speed bumps is in sight! **Implications** - The goal behind the [retractable speed bumps](https://www.trendhunter.com/trends/flipcare) is the [reduction of pollution and energy consumption](https://www.trendhunter.com/trends/rheinmetall-curb-charger). By encouraging drivers to driver safer and slower, cars will make fewer starts and stops, reducing the car's waste numbers. ## Trend Insights (Trend Hunter) - Score: 1.6/10 - Popularity: 14% | Activity: 27% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Autos](https://www.trendhunter.com/autos) ## Key Themes ### What Makes This Trend Stand Out - **Flattening Speed Bumps:** Innovative speed bumps that flatten out when crossed at low speeds, rewarding slow drivers and reducing vehicle starts and stops. - **Safer Driving Incentives:** Implementing speed bumps that provide a smooth ride for cautious drivers, encouraging them to drive at lower speeds and reducing pollution and energy consumption. - **Efficiency in Traffic Calming:** Retractable speed bumps that only affect drivers exceeding certain speeds, allowing smooth travel for slower drivers while promoting safer driving habits. ### Sectors Adopting This - **Transportation:** The transportation industry can adopt flattening speed bumps to promote safer driving and reduce pollution and energy consumption. - **Automotive:** Car manufacturers can collaborate with designers to include retractable speed bumps as a safety feature, incentivizing drivers to stay within speed limits. - **Urban Planning:** Urban planners can incorporate the use of retractable speed bumps to create more efficient traffic calming measures that reduce pollution and encourage safer driving habits. ## Related on Trend Hunter - [Pedestrian-Detecting Crosswalks](https://www.trendhunter.com/trends/smart-pedestrian-crosswalk.md) - [App Usage Limiters](https://www.trendhunter.com/trends/speedbump.md) - [Flatpack Traffic Cones](https://www.trendhunter.com/trends/apiece-traffic-cone.md) - [Transforming Smart Vehicle Tires](https://www.trendhunter.com/trends/conqueror-tire.md) - [Bump-Absorbing Electric Motorbikes](https://www.trendhunter.com/trends/offroad-motorbikes.md) - [Urban Robot Traffic Safety](https://www.trendhunter.com/trends/polis.md) - [Traffic Light-Inspired Benches](https://www.trendhunter.com/trends/traffic-light-bench.md) - [Bouncy Car Suspension Systems](https://www.trendhunter.com/trends/car-suspension-system.md) - [Transforming Commuter Kick Scooters](https://www.trendhunter.com/trends/beam-scooter.md)
