I didn't know snakes could run!!! Haha..
On a more serious note joe, I believe what you just said is a myth. In Australia we don't have any snakes that I'm aware of that can spit venom, most (if not all) our snakes rely on glands to be compressed for the delivery of venom, imagine it as a wet sponge that sits above the fang if that is not squashed no moisture will come out. For this reason if a snake strikes and misses you have absolutely no fear at all of any symptoms arising. A good proportion of our snakes have quite small fangs that are set back quite far in the jaw so If you're unfortunate but lucky at the same time you can even get what they call a dry bite, this is where you have been bitten and may show puncture wounds from front teeth (or even the fangs) but the chomp so to speak was not enough to deliver any venom, although even if this were to happen I'd be taking myself to hospital for a professional opinion for safety's sake. I'm not having a stab at you but... I'm on the other side of the fence to the people with the "only good snakes a dead snake" attitude. I have pet snakes, and have from a young age caught and played with anything that I could get my hands on as a kid really, from scorpions to tiger snakes, and skinks to goannas and I'll tell you not one animal has ever tried to attack me before I had provoked it. If you back track and give a few meters wide berth to a snake and return in a couple minutes it'll be gone, leave sleeping dogs lie is a good cliche when it comes to snakes and your safety, the only exception may be the taipan of which I have no experience with but have been notoriously known to attack when disturbed. Long story short I think your information is misinformed and only provokes more fear into an animal that doesn't need it. Gators are definately a good precaution and something I've always considered, as is a stick or you're coil if detecting, a snakes going to strike at the nearest object 90% of the time if it comes to that so something that is held between you and a snake while you walk by is another very good idea.
