It is a noble thing to save so much critters (small animals) but at the same time sometimes people just do not notice when the cat dashes through.
The only sad part of cats is that they have a very wild nature (especially male ones) and they will wander until they are satisfied.
I agree humans should be more attentive when driving in housing areas to avoid hitting pets and other animals; and that, in general, humans need to really learn in basics.
(I pray hard that the driver that hit your cat was not texting or speeding... that'll be really sad)
