There are different kinds of lidars that use different wavelengths and sensing methods. For self driving car use, the difference between a small lidar that's on a phone or vacuum cleaner and the one on a car would be the amount of power used such that objects far away can be detected, and the ability to operate in automotive environments (noisy power supply, high temperatures, lots of vibration).
