Many companies are working on autonomous cars already. We have covered a bunch of awesome self-driving cars in the past. These driverless golf carts by SMART members are also interesting. They can get you around without crashing into obstacles. These golf carts have lizard-like sensors for obstacle detection and collision avoidance. They can be used as private vehicles or as a part of a shared transportation system.
In the future, you will be able to summon robot cars from your smartphone to get around safely. It is nice to see that various companies are working on this idea already.
