You do not have to look too closely to see that the new sensors that mount the Lexus SUVs on the roof are different from the previous models seen in images and videos. In this case the LIDAR system is much more cumbersome And it's different from the one they used in the initial tests on these vehicles.
The LIDAR explained in a simple and fast way for those who do not know, is the set of sensors and cameras that constantly receive / send data and help the computer to use the autonomous driving of a vehicle.
This is a video that has been leaked on the net you can see one of these Lexus models used by Apple with the new LIDAR system. The detail of the car itself is also important and we are seeing the new 2017 models of these Lexus:
It is clearly seen that in the front of the vehicle there are two people seated and one of them is on the driver's side with the hand on the steering wheel, so we can confirm that it is totally legal tests with a minimum of two people in each vehicle. It is logical to think that Apple has been investigating this technology for a long time but the guys from Cupertino would be one step behind the competition and they also do not seem to be in a hurry in this Titan project of which the CEO of Apple himself confirmed its existence.
It has also been ruled out for now that Apple is fully involved in the automotive industry, but we work on the software that any car can install. Apple does not want to launch an initial software like Apple Maps with numerous bugs, and for that reason it has to take maximum care of the details of the project so we are sure that it will not be something that arrives immediately but it seems clear that it will eventually arrive.
