The latest company to join the race is Intel, the giant chipmaker that it's building a fleet of 100 self-driving vehicles. The first cars will hit the streets by the end of the year. The move follows Intel's $15.3 billion acquisition of Mobileye, an Israeli based company that makes computer vision technology used for self-driving vehicles. The fleet of 100 cars will include multiple brands and vehicle types to show how the Intel and Mobileye technology can be used by different car makers and other potential customers. Intel said the test cars will be "Level 4", referring to the NHTSA classification of autonomous vehicles. Level 4 is the second highest rating and means the car is fully autonomous and is designed to perform all critical driving functions. The cars will be tested in the United States, Israel, and Europe. The idea is to test and train the fleet in geographically diverse places so that the cars can be deployed anywhere in the world.
