yes and no, it is easier to do it. but large trucks are a bigger hazard on the road the a small car, they can break the middle barrier, can do a lot more damage on the road. the fines for the drivers and the companies are allot stricter.
they have to get it 100% all the time or they cannot put it on the road. One glitch and you have a 25t missile on the highway. Imagine the chaos that can cause, and imagine the liability of the company operating that truck.
while it is easier in ideal conditions, it is not easy in real world.
Believe it or not, making sure the truck fails safe and keeping it under control are far easier problems for a computer to solve than predicting if a pedestrian will jump in front of a car.
But I'm not sure it makes any difference. You aren't "supposed" to find pedestrians in a road, but you'll certainly find them, and the truck must be able to deal with them.
At interstate highway speeds, there is no dodging an unexpected pedestrian who jumps out into the road. Swerving creates greater danger - an overturned truck is likely to cause other severe accidents. Pretty much all a truck driver can do is apply moderate braking, lay on the horn, and stay in their lane.
