Yup, and there are thousands of animal strikes every year in my state alone. Every three days or so there's fresh roadkill on the side of the road when I drive into work.

Night, day, twilight - a bicyclist can only increase their likelyhood of surviving their trip by adding reflectors and wearing bright clothing.

In a lot of states, a cyclist riding at night without a rear light is also breaking the law and at fault.

Yep, and I've still managed to avoid hitting all of those I've encountered by driving slower at night in places where I can't see as far ahead of my vehicle.

I'm not disagreeing that it's your responsibility to not crash, but as noted farther up - people hit wildlife all the time.

It's pretty rare for somebody who hits a deer to be charged with reckless driving, so it's not like there is actually an absolute responsibility to never out drive your headlights.

Besides the legal aspects, anyone riding a bike after dark without any illumination is being irresponsible. Whether the car is at fault or not, it's not going to be the guy in the car who dies from it.

So far. Just hope that you're never distracted at just the wrong time. It only takes a couple of seconds to overrun your headlights, even at lower speeds.

A car with high beams cresting a hill behind you. A car with high beams cresting the hill in front of you. An animal. A drink. A radio station change. A text message.

But a light or bright clothes won't change that situation - if you're distracted or are coming up to the top of a hill reflection won't save the biker.

It’s the difference between having 4 seconds to avoid a collision, and having 30 or more (I’ve seen a few well outfitted bikers over a mile away before).

Reflectors make that big of a difference; they don’t look or move naturally, and thus play well to our night vision strengths, even to a distracted driver.

I agree that bicyclists should outfit their bikes to be visible in the conditions they will encounter. But it it's also our responsibility as drivers to maintain a sense of the unseen hazards of our environment so as to avoid killing people who aren't as savvy as us. I wouldn't personally cycle without lights or reflectors but the fact that tons of people do means that if I'm not sure then I must assume there's someone out there.

Also, sometimes people are walking in dark clothes on the road. Maybe their car broke down. Maybe they're trick or treating. Maybe they were out later than expected. Regardless, demanding other people dress like the world is a construction site so you can drive fast is impolite.
