lets say you're moving at 55mph which is 80 feet per second. your low beams project ahead about 50-60 feet visibility...but you're covering 50 feet in under one second now. so you see something 60 feet ahead, you have less than one second to react and hit the brake pedal. maybe if you drive with your left foot hovering over the brake pedal all the time it would work out? lets say you have your high beams on, and now you can see 100-120ft down the road with clear visibility, you now have about 1.3 seconds to react and hit the brake pedal, whats the 60-0 stopping distance of a 3G Eclipse? 135 ft. even going 5 over the speed limit, with your high beams on at night and seeing the deer 120ft out and reacting in under one second, you'll probably hit that deer unless you have upgraded brakes, matching tires, or can swerve at the right moment to miss it and not run off the road. granted by the time you're on the deer you're probably only going about 20-30mph so swerving isnt going to be such a problem, however deer are unpredictable and theres often more than one.__________________
a little math changes for the corolla, they have a slightly (10ft or less) stopping distance, the rest still rings true. dont speed at night!
you could argue that you can see further than 100ft with your highbeams, you can...but you've got less than a second to figure out what you're seeing and decide what to do about it. my high beams can light things up 200-400ft away with ease, but that doesnt mean that traveling at 60mph i can discern what they are in under one second.
