Presumably you are talking about driving while over the LEGAL limit.
To my mind there is a lot of difference between,being one point over the limit,and being twice or three times the limit.
punishment must reflect that fact,as regards paying increasd insurance it does not as far as I am aware
the problem to some extent rests with the government,I live in rural Ireland,there is no public transport,in practice there are no taxis,it is no longer feasible to take a pony and cart,to the pub,because there are some very dangerous sober drivers,very dangerous boy racers,etc,it is in fact quite dangerous to walk down narrow country lanes even with illuminated clothing.
but this is what I am forced to do,if I am killed by a sober maniac driver,who is driving too fast for the road conditions,I feel he should be treated in exctly the same way as a driver who kills somebody while over the limit.

Personally, I think that dangerous driving which results in death,whether the person be sober, drunk,or high on drugs,should be treated equally severely.
if someone takes a life while driving dangerously while sober,or being under the influence of drink or drugs.they should be treated equally severely.
