The word accident is used WAaay too loosely around here, it's not like oops I typed the wrong letter accidently and have a spelling mistake... What the punishment should be seems to be more of a cultural difference, but not murder persay, as mentioned there's dozens of reasons why someone could run a person down who is on the side of the road. BUT MOST of them ARE CAUSED, even the Dr. who saved a dozen lives working 2 days not sleeping "caused" the "accident" by trying to drive home, should he be held responsible, how responsible? 1 month 1 year, 5 years, 10+ years in jail for killing a person is a different question... But responsible he is, IMO It's like deciding not to wear a helmet, you crash and get a big rash and a goose egg instead of nothing... That was caused, it didn't "just happen".
