Interesting article
Maniac. Thought you were choosing between them for a new car at first!
After reading this, I have a maybe stupid question. If the electrics are automatically cut in some cars, then that would mean you wouldn't be able to put windows down (like if you could and needed to climb out of car if in a ditch and the door is jammed). I know this sounds far fetched but, eek! Would you have to smash the window

(extreme and don't have that strong an elbow!?) or try start the engine?
Never thought I would ask this other question, and it's a question my Mum might have raised before and only now do I think 'that's a point'; if you have auto-locking doors, like when you pull away, or like me being a woman you lock your car doors, if you had an accident like the type in the article and your car is the type that cuts the electrics or your engine is off, could you unlock the car door from the inside?! I know on the Fiesta which has auto-lock after pulling away it unlocks after you switch the engine off, but what about other modern cars? :?
