The worst case scenario for the Volvo is this:
The currently dragging / rubbing brake pads overheat and disintegrate
They and/or their hardware jam in the wheel
The wheel comes to a complete stop at 80 MPH
The effect of a suddenly locked rear wheel causes the rear axle to get ripped out of its mounts
The car veers sideways and rolls
Down a bank and then burst into flames
And lands in a river, upside down
Out of sight of anyone
You die.
Alone.

...

Well, you did ask for the worst case scenario

I have spoken to Volvo mechs who have seen the first 5 steps happen - where the axle is ripped out on the motorway by a jammed wheel.

The rest I made up - but you get the message.

Because you say that you drove with the parking brake applied that would seem to be why the wheel was hot (other posible causes could be a frozen caliper or failed wheel bearing).

The parking brake has two shoes inside the drum (which is part of the disc). One shoe leads forward , the other rearward. It may be that the forward leading shoe bcame so hot that it has stuck ON.

Try driving backward for a few yards. It may free the shoe. Jack up the wheel to check if it is still binding. If it is then the parking brakes must be serviced.
