Nope, sorry, nuh-uh, NEVER.
I'll echo what the first few posters said in that you should NEVER swerve for animals.
Trust me, I'm a HUGE animal-lover (NOT like that...
) but I have decided that I simply will not swerve for anything smaller than a golden retriever. (Gee, that sounds an awful lot like, "I grew up shooting guns, but I think all guns should be banned."
)
As one poster knows from firsthand experience, it can cost you your life. (Or come darn close to it!)
I'm terribly sorry that happened to you, and I think you a wonderful person for going back and putting the poor thing out of its misery, but the driver did the right thing by not swerving.
I don't care if it IS "only" a residential area w/25 mph limit; I STILL DO NOT SWERVE or brake suddenly.
If anything, a residential area is the LAST place you would want to swerve or engage in other sudden movements, given that there are probably kids around.
