Designed to create new possibilities for customers, the Honda NeuV (New Electric Urban Vehicle) is an automated EV mini-vehicle concept with artificial intelligence (AI) that aids driver decision-making and can generate income for its owner through autonomous ride-sharing and the ability to sell energy back to the electric grid during periods of low use.

 

They also showed off something called "Riding Assist", which is a self-leveling feature for motorcycles. Honda showed a demonstration of it:

In a global debut at CES, Honda unveiled its Riding Assist technology, which leverages Honda’s robotics technology to create a self-balancing motorcycle that greatly reduces the possibility of falling over while the motorcycle is at rest.

 

Meanwhile, Volkswagen was giving show-goers a preview of something called "Volkswagen User ID", which they say can carry a driver's preferences across multiple vehicles, and adjust things like entertainment and display configurations.

They also made upgrades to their "Digital Key" feature, adding more functionality and personalization.

And finally Audi announced a partnerhship with NVIDIA, and promised to have fully autonomous vehicles on the road by 2020.
