Jaguar Land Rover has devised a new remote-controlled Range Rover which can be steered by smartphone.
JLR has unveiled its prototype 'multi-point turn' Range Rover Sport which can be controlled by an app including steering, accelerator and brakes.
It also allows the driver to walk alongside the car while still in control of the vehicle.
The driver turns a virtual steering wheel image on the smartphone's touchscreen - using similar finger-tip controls on the screen to apply the brakes and throttle - and the car follows every command like a full-sized remote-controlled toy car.
The driver could use the smartphone to reverse out of a parking space if a vehicle is too close for them to open the door or allow the driver to guide the car over obstacles from outside the vehicle.
The remote control will only operate if the user is within ten metres of the car and if the smart key can be detected.
The system will stop the vehicle if the driver moves out of range or stands too close.
Wolfgang Epple, director of research and technology at Jaguar Land Rover, said: "Getting a car out of a tricky parking manoeuvre can be a stressful experience for any driver.
"A remote control car or a vehicle that can autonomously turn in the road demonstrates how we could use these new technologies to reduce the tedious parts of driving and improve road safety.
"Research into technologies like these won't only help us deliver an autonomous car. They will help make real driving safer and more enjoyable.
"The same sensors and systems that will help an autonomous car make the right decisions will assist the driver and enhance the experience to help prevent accidents.
"Autonomous car technologies will not take away the fun of driving. Because our customers drive in all terrains and in all weathers, any future autonomous Jaguar or Land Rover must be as capable on rough tracks and unpaved roads as it would be on city streets."
