Rinspeed has revealed its latest autonomous car – the BMW i3-based Budii. The new concept features technology from the Swiss company’s 'idea factory' – including a robotic arm that literally hands over the steering wheel to the occupants when they fancy some fun at the wheel. Other quirky features include a function enabling the car to follow you when you go for a jog – and then you can switch on the taps to run a bath so it’s ready when you get home. The Rinspeed Budii will make its debut at the Geneva Motor Show on March 3.
