Rusty cars are usually a bit weaker then ones without rust. It chips of easily and so that is why a rusty car is dangerous. Especially if the main body or chassis is rusty. Weakness on the chassis mainly could be a definite killer to a car. That would mean changing the chassis. I would just get a new car by then.
yes if the structural integrity is compromised like the frame being rusted out as an example
Yes, it is.
Surface rust isn't dangerous, cancerous rust on the frame can be dangerous because the car could snap in half depending on the extent of the rust. The best solution usually is just to get a new car because the frame usually isn't worth fixing. In my state they consider it dangerous because if you get stuck in snow they fear exhaust entering the cabin and killing its occupants. Rust holes of any kind will fail your inspection.
They may become unsafe to drive due to rust weakening parts of the car.
you cant drive your car if you have hole in your engine because your engine is a propeller for your car.
Yes.
its because of accident

it could be dangerous and the car might fall apart and look very used bent and rusty brown bubbly and probaly wont go
The car is safe due to the strength of the body. If it is rusty the strength goes away quickly. Also all the brake and steering parts are mounted to pieces that rust also.
