Just as there are many companies testing different models of autonomous cars, and some of them offering autonomous taxi services in some cities, the case of autonomous trucks is going a little slower.
A truck is like a car, but much bigger and with much more weight, with which its problems are much more complex. In the first place, due to the inertia of the weight it carries, it makes errors that occur take longer to be corrected; and also due to their size and weight, the possible accidents they generate are much more dangerous.
That is why companies like Waymo, with a lot of experience in autonomous cars, took several years to start experimenting with autonomous trucks, and they still do so in very limited cases and applications.
That is why I have read with surprise and pleasure that the truck company Scania is going to start experimenting on the road with an autonomous truck model. It's a 40-ton truck-trailer, and initially there will be a driver close to the steering wheel to correct any problems that arise.
In the photo above you can see how the tractor cabin is, with some sensors placed on the roof of it. It has Lidars, several cameras, high-precision GPS, etc... to provide precise information to the control computer.
They are going to carry out tests on the roads of Sweden and will use routes of about 300 km to take products between logistics centers. Over time, and with the improvement of the control system, they plan to also experiment in other countries, as Scania sells trucks all over the world.

If fully autonomous cars are far away, I think trucks are much further away. But both one and the other will gradually achieve improvements that can be applied to cars and trucks driven by people, so as to increase their safety and make driving easier.
What is clear is that automation, with varying degrees and variations, has reached the world of automobiles and trucks. And their costs will become cheaper and the various improvements achieved will be applied to the different models that were being manufactured, as time goes by.
Like so many things, everything is a matter of time.
