Although they can perform a number of tasks of which no individual human is capable, they are not intellects and there are many fields in which they perform much worse than a human brain - for example, you can't have real-time conversation with the scientific community.
The kerb or curb weight is the weight of the vehicle minus any passengers or cargo. This refers to the weight of the car if it was parked on the curb without anything in it. It still has all the necessary equipment and fuel but doesn't have any added weight that isn't built into the car. The gross weight refers to the car's total weight when it has added passengers and cargo.
The gross vehicle weight rating (GVWR) is assigned by the vehicle manufacturer or finisher. Please note that the GVWR on your DMV paperwork may not be accurate, and should not be reported. The GVWR required for the regulation represents the maximum weight of the vehicle and what it can carry when fully loaded.
