Car technology is being showcased at CES 2015 in Las Vegas, as manufacturers use more advanced systems to automate driver assistance and in-car entertainment.
Several major technology and automotive brands have presented their take on using the latest tech to improve driver experience and comfort, or to eliminate the driving side of motoring altogether with autonomous driving systems.
Below are some of the most interesting uses of car technology to catch our eye at CES 2015.
Mercedes has long been known for luxury cars that combine performance with premium quality, and has now revealed a concept car that drives itself.
The F 015 Luxury in Motion (pictured above) has a more futuristic look than Google's much discussed driverless car, offering a slicker and sharper shape and lines that exude Mercedes' luxury roots.
The front seats can swivel so that front passengers can face those in the rear, demonstrating Mercedes' aim to provide a "lounge-like interior".
The company said that driverless technology will enable travellers to work or relax while effectively being chauffeured by the car's autonomous systems.
Mercedes kept quiet on the hardware powering the driverless systems, but the car has six screens integrated into the instrument, rear and side panels, turning the interior into cocoon of digital displays controlled by touch, gesture and eye-tracking. Even the windows can act as interactive displays.
The F 015 concept is unlikely to find its way on to the road in its current form, but it demonstrates the direction Mercedes is taking in its approach to driverless cars.
Audi is arguably further ahead in its development of driverless systems than Mercedes, and has been working on autonomous driving systems for some time with what it calls Piloted Driving.
The company showed off its self-driving technology with an A7 Sportback that piloted itself across 550 miles of US highway on the journey from San Francisco to Las Vegas.
Piloted Driving effectively bridges the gap between traditional cruise control and full car autonomy. The system enables the car to drive itself along highways using several 3D cameras, a laser scanner and five radars.
The system is not yet sufficiently refined to negotiate city streets with their unpredictable hazards and obstacles, so an alert sounds and control is handed back to the driver.
If the driver does not take control the Piloted Driving system switches on the hazard lights and brings the car to a steady stop.
Audi may not have created a fully autonomous car, but it is providing a system that looks likely to be road-ready in a few years, and offers a good stepping stone to the driverless car.
BMW also showcased its own car technology at CES, but has concentrated on automatic safety and driver assistance features, rather than the driverless element of automation.
The company challenged CES attendees to crash an i3 equipped with BMW's ActiveAssist collision avoidance system dotted with concealed external laser sensors.
Unlike traditional ultrasonic parking sensors, the ActiveAssist system pinpoints obstacles and collision risks and makes the car react accordingly.
If the car is heading towards an obstacle or cutting a corner in a way that presents a risk of collision, the system will override a driver's accelerator input and apply the brakes. The accuracy of the laser sensors means a collision can be avoided by mere inches.
BMW also demonstrated an automatic valet system which uses a BMW app developed for Samsung's Gear S smartwatch to allow an i3 to park itself. This also works in reverse, allowing the driver to summon the car from its parking space.
Other BMW technologies on show included touch and gesture control for its iDrive infotainment system, and daylight-mimicking laser headlamps that can highlight animals or people and bring them to the driver's attention.
Like Audi, BMW has not created a fully driverless car but is effectively demonstrating systems that pave the way for autonomous vehicles.
Volkswagen showcased similar technologies to its fellow German carmakers, but also revealed new infotainment systems.
The second generation of VW's modular infotainment platform integrates three major app and smartphone mirroring interfaces - Apple CarPlay, Android Auto, and MirrorLink - into one unit under VW's App-Connect brand.
The option to use multiple interfaces allows mobile devices from numerous brands to connect and interact with an infotainment system without needing platform-specific devices.
VW's infotainment platform is due to launch later in 2015, and is indicative of the growing relationship between in-car technology and mobile devices.
The automotive arm of audio specialist Harman Kardon revealed its Individual Sound Zones (ISZ) in-car audio technology that enables drivers and passengers to create their own 'sonic zones'.
ISZ uses headrest speakers in a car's regular audio system combined with digital signal processing to segregate different parts of a car for different audio sources, allowing, for example, a front passenger to make a phone call while a rear passenger listens to music.
The system channels audio in a way that provides little interference or crossover between the sources, ensuring that relevant audio is tailored and boosted to individual passengers.
Qualcomm is known for processors commonly found in mobile devices, but showcased hardware at CES 2015 designed to power the latest in-car infotainment systems.
The company used cars from Maserati and Cadillac to demonstrate how its Snapdragon processor can power high resolution displays, collision systems, in-car Wi-Fi, LTE broadcasting and audio streaming.
Qualcomm is not the only chipmaker getting involved in car technology. Nvidia also revealed its ambitions at CES 2015 to integrate a mobile supercomputer processor into cars of the future.
It is clear from the systems and vehicles showcased at CES 2015 that automating the process of driving is a clear focus for many carmakers.
The future of completely autonomous cars may be left to Google and its driverless ambitions, but the major car brands are giving vehicles more autonomy without requiring motorists to take a leap of faith and completely relinquish control.
Measuring the reaction to autonomous vehicles may not be as far away as some manufacturers predict, as the UK government has given the go-ahead for driverless cars to be trialled on public roads in 2015.
