Answer 1

Step-by-step explanation:

Autonomous cars rely on sensors, actuators, complex algorithms, machine learning systems, and powerful processors to execute software. ... Lidar (light detection and ranging) sensors bounce pulses of light off the car's surroundings to measure distances, detect road edges, and identify lane markings.

Answer 2

They can use a camera to read the limit from signs (using a form recognition algorithm). Cars will also have to take in account the speed of surrounding cars and could cross-check with a GPS database.
