I wasn't aware the hood cable breaking was an issue. I've owned over 100 cars and have never had a hood latch cable break.
Sounds like a solution in search of a problem to me.
Good idea, all you need to do to start is open the hood and…Ops!Actually, you just need to remove the engine/cradle then you can pop the hood from underneath. Just isn't a good option if you're in a hurry.
