Just call the police.
They'll tow you to somewhere safe off the next exit.
Has never accured to me
The one time it happened to me I was in process of having two premium banks so had rac with and aa with the other so called them both and raced them to my location
Ironically cancelled one as the other said was 10 mins away and the cancelled one showed up first
Had a full size spare in that car which left to them to fix then carried on
