Full throttle

This is the world’s smartest throttle pedal. Created by the boffins at Bosch, this “active gas pedal” communicates with the driver by buzzing, tapping or even applying counter-pressure to help you drive more efficiently. Feedback is sent to your right foot if you accelerate too aggressively or exceed the speed limit, while other signals tell the driver when to shift gears and when to coast to save juice. Bosch says it should reduce your fuel bill by seven percent. It’s a boon for safety too; it warns drivers to slow for corners or of potential traffic hazards by connecting to your car’s sat-nav and other assist systems.
