Robot trucks might work in like middle of nowhere North Dakota or Wyoming. But once it comes near a city, it gets extremely complicated
How would a Robot truck be able to drive in traffic? How much electronic sensors would a truck have to have in order for it to not bump into anything? What if one of the sensors suddenly goes out and a truck is driving 80mph in oncoming traffic?
What if a robot truck on the road, and the route or destination suddenly changes (which always happens). How is it gonna communicate to the robot truck if something wrong with it? When a simple phone call from a human driver would be 100x easier
And you can even go to the simplest thing of backing into a dock. There is no place in a dock where you can have perfect conditions, which a robot truck needs. The driveway gonna be lopsided as fukk, there's rocks on the ground, the dock itself is old and lopsided, there could be snow or mud on the ground, the lines on the pavement for the truck to guide itself to park could be shaded out
This is what nerds in their air conditioned offices never consider
