You are looking only for sriving negative aspects. But the fact is there are even more serious side effects of drinking. Beating wife is a common thing what we read in news papers, due to this many families are getting divided.
According to me drinking is the root cause of many evil things. Eg: Generally rapist will be drunk, check out the statistics.
So my question is why ban only driving and why not ban drinking itself. Many religions are also against drinking and Indian are one of most religious people compare to the rest of the world.
So ahead and BAN DRINKING itself. This is practicle, just check out in Saudi Arabia.
