Truthfully I didn't think much about it, but yes I assumed that was their weight, in the same way that a heavy-weight boxer fights in a particular weight class.
If you thought the large trucks people call half ton weight only 1000 lbs, you have such a disconnect with reality and the physical world that I can't even relate. If a half ton Chevy truck weighs 1000 lbs, what did you think a Honda Civic weighs? As much as the driver and passenger?
Some people don’t give much thought to trucking or weights or even vehicles in general; Their connection to reality isn’t based on needing to know those things. Some people even live in places without trucks at all. The world is pretty diverse!
