From Acura to Volvo, more and more car companies are getting into the game of self-driving tech, and it’s now easier — and more affordable — than ever to buy a car that basically drives itself.

Today, the most advanced systems on sale are classified as level two, which bundle driver-assistance features and safety equipment but don’t quite make the driver redundant — yet.
