No need for hysteria over Songkran deaths

The annual hysteria over Songkran road deaths is puzzling.  Thailand is a Buddhist country, right? Buddhists believe in reincarnation, right? So all those dead people will be reborn. What’s the fuss about?
Unlike the gloomy-Gus one-life religions (like Judaism, Christianity and Islam), Buddhism offers people a second shot at life.  Not only a second shot, but an infinite number of shots, so long as the karmic wheel keeps rolling.
I don’t pretend to understand the theory of karma fully. But logic suggests that if a person accumulates bad karma by doing evil, suffering ought to expiate it. Just as criminals expiate their crimes by doing jail time, so evildoers must be able to expiate their bad karma by suffering. This will facilitate their rebirth into a happier state. By dying horribly in a gruesome road accident, the petty thief and drug dealer living in a Klong Toei slum will have his karmic slate considerably cleansed.  He might be reborn as a megarich fat-cat tycoon living on Sukhumvit, with dozens of minor wives, summer homes in Chiang Mai, Phuket and Acapulco, and a Benz in every garage. So suffering is good, it’s a karmic cleansing agent, and those who inflict it (all those drunk drivers) ought to get a medal. In fact, by propelling their victims to a happier state of being, the drunk drivers may get some of their own bad karma cleansed.
The Songkran carnage is a win-win situation for everybody, folks.  The only people who really get hurt are the grieving relatives of the dead, who don’t understand the situation.  
If there’s a flaw in my reasoning, I’d like to hear about it.
