2005 and I was on Mat leave, DS was 16 weeks old. I had an interview with GAP in London. I went to get in my car to drive and Ex twunt DH said don't go over 80mph or it makes a knocking sound, but it drives ok. 
(He'd bloody damaged my beloved sports car pissing about in it and not told me or fixed it.)
Anyhow on the motorway as it was too late to do anything. Car starts driving really strangely so I slow right down in the inner lane. Suddenly I see flames licking the windows, I pull in and the engine (in the back) is on fire, black smoke everywhere.
I try to get out of the car. Then realise my phone wallet etc is on the passenger seat. I open the door to grab them and a guy grabs me by the waist and pulls me from the car just as the flames really take hold.
He was a lorry driver who'd seen what had happened and pulled infront of me, whilst radioing another driver to pull in behind. The other guy called the fire brigade and police.
He dragged me away from the car as the flames were reaching everywhere, and black spumes of smoke covered us.
Lifted me into his cab and climbed in. Poured me a cup of tea from his thermos and strangely lit me a cigarette. He was about to bollock me gently but he saw my then Puss in Boots eyes in my sooty smeared face.
Give me a hug and called me cariad. This made me burst into tears as I am Welsh. Told him and he pulled out a tin of Welsh cakes from the back, his wife had made that day.
So we sat and chatted until the police took me to their car.
I never got the chance to find out his name, or the other guy. I was in shock and didn't even see the haulage company name.
But if he hadn't pulled me away I might have left DS motherless that day.
He was a little Welsh Guardian Angel. ????
