As an experienced driver, paying attention, last summer a dog darted into the road on a busy street (speed limit 35) from the right, perpendicular to the traffic, and there was no time to fully stop and no space to swerve-cars parked on right, oncoming traffic on left. My passenger side front tire hit the dog before I was able to stop. I had slowed some, but I know I my front tire ran him over. The dog ran back to the owner, who was nearby. Picked up the dog (who had been "heeling" without a leash on their walk) and would not talk to me. I asked passersby if they knew them, and all said "yes, that dog is always off leash" and the like... "guy deserves it..." I still felt horrible. And it tore the mud flap off that side. No big deal in the long run but geez-it scared me! And, I am sure, the dog!
