Not saying you're wrong in general but

if you need to stop on any kind of hill, you have to be aware your gonna need half a car length or more to get into gear where your just going to be falling down that hill while you convince yourself you don't need to panic and you will catch the gear before you're past the point of no return

My shitty Toyota Aygo has a hill start assist thing and it works very well. Basically when you release the brake at 0 km/h it holds it for a few seconds or until you reach the slip point of your first gear. Also handbrake start is right there in the OP, (and a mandatory part of drivers ed over here)
