I doubt this was about environmentalism. Something large splatters against your windshield out of nowhere, and you react. Chances are that OP hit the brakes before identifying the bird.

what are you on about? Depending on the size of the bird, a bird could smash your windshield if you ran into it too fast. Slamming on the brakes could easily be a very reasonable reaction. Why is it ok to slam on your brakes for a small animal crossing the road (which you'll just kill but won't endanger you), but it's not ok to slam on the brakes for a bird that could potentially shatter the windscreen and either a) injure someone inside the car or b) make the windscreen too damaged to drive with? Also, you obviously know nothing about driving rules. No matter what speed you are going at, it is your responsibility to make sure you allow enough space between you and the car in front of you to react. This means you alter that distance according to the speed you are going. eg. if you are driving at 20km/hr the distance you need to leave between you and the next car would be much shorter than if you were driving 100km/hr. If you are unable to stop when the person in front slams on their brakes, then that is your fault because you did not leave enough time for your reaction. What if the person in front of you had to slam on their brakes because a child ran out into the road? Would you still say it's their fault because all the other traffic was "flowing smoothly" and you weren't "expecting" that?

did i argue about the rules of driving.. did i say anywhere that you should ride a foot behind the car in front of you.. i know the rules of the road and that when you hit the car in front of you from behind its your fault.. i never argued that once.. the point is that the op caused the accident even if it wasn't legally her fault since she got hit from behind... how the hell do you compare a kid on the road to a bird.. obviously your gonna slam the breaks if you see a kid in front of you on the road... the bird had already hit her windshield and then she slammed her breaks like an idiot.. and how big are the birds that hit your windshield? a bird is not gonna break your windshield.. a little common sense goes a long way.. stop arguing for the sake of arguing because its obvious the op didn't react properly to the situation

You're a man and you have bad grammar. I just thought I'd post a useless comment on your useless comment.

that's the biggest load of rubbish ever. Slamming on your brakes to avoid hitting something is not dangerous driving, nor is it unnecessarily impeding the flow of traffic. Impeding the flow of traffic might, for example, be driving too slowly because you're busy putting your makeup on or trying to text a friend, or just coz you're too distracted listening to your music or talking to your passenger. Use a bit of common sense.

Actually you're wrong. At least in the UK, if you slam on your breaks / swerve to miss an animal, and it causes a danger to other road uses, then you shouldn't have done it. You're meant to keep on going and hit it.

maybe you should use a little common sense... a normal reaction to slam the brakes when an animal is infront of you is if that animal is like a deer or something.. not a bird.. why must you be so stubborn.. can't people just admit the op reacted wrong and caused an accident.. they teach you in driving school how to react in situations like this.. that's the point of driving school to avoid getting into accidents like these... clearly op forgot what she was taught at driving school
