I saw a animal get run over today it really upset me :(?

Today was my birthday and i was coming back home from a family meal (it was my 17th bday) and i saw there 2 pigeons on the otherside of the road like walking around in the road, they seemed quite happy together. My dad was driving and as i turned round to look out of the back window i saw this car going towards them and i thought it would slow down or they would fly out of the way but the car seemed to speed up and one of the pigeons moved and the other one went to move but wasnt fast enough and i saw feathers go everywhere and the car just drove straight over it and went speeding off, it didnt even stop! I know many people dont like pigeons but if it was me i would of slowed down and stopped if i had hit it! And after i saw it get hit an the car drove off it was flapping its wings and its mate was there with it! It made me cry because i saw it all and the driver was so heartless not to even stop! I wanted to get out of the car and run to see if it was oki but my dad just kept driving and my family didnt seem bothered which annoyed me! This ruined the rest of my birthday as i cried about it an i kept seeing the image in my mind of when it got run over and it made me feel really sad and depressed :( So what im asking is would you ever run over a animal and if you did would you stop and help it? If not you are a very heartless and cruel person!!!!
