AIBU to put a blanket over my lap and knees when driving?

Yes.

Very

No.
I've got leather seats. They are bloody freezing, so I sit on a blanket atm.

Totally

A blanket may fall off and get in the way of the controls.

If you wore a long coat, that would also keep you warm, without being potentially dangerous.

Probably. It could slip off, or restrict your legs/feet. Get some longjohns

YABU. What if it slips down onto the pedals? Why not just put the heater on?

Yes. If it falls off and gets tangled round your pedals it’s a safety hazard not just to you but to other road users.

Wear a coat or get seat covers.

I've actually seen heated blankets advertised for use while driving and shaped so as not to interfere with controls.
