Google is now exploring fully self-driving cars, even though they're illegal in California.
The cars are so tiny that they can fit inside a standard trailer.
These cars don't have a steering wheel, accelerator pedals, or break pedals.
All you have to do is push a button to make it go.
The cars require zero human intervention, whatsoever.
That's because safety is the most important factor Google took into consideration.
The cars have sensors that remove blind spots and can detect objects out to a distance of more than two football fields.
These prototype cars can only go up to 25 mph.
Inside the car, there are just two seats.
Google plans to build about 100 of these prototypes.
Starting this summer, Google's safety drivers will start testing out the versions that have manual controls.
In the next couple of years, Google hopes to run a small pilot program in California.
