Accident-free Highways

I've been asking this to a lot of my friends for some time now and one of them suggested that I post it online. Anyway, here goes.

Suppose you were a president of a nation (or monarch of a kingdom, or emperor/empress of an empire, wherever you live) Now, suppose, too, that a mage (I prefer sorcerers but "mage" was the first word that popped into my mind back then) approached you and offered you the following:

1. He will cast a spell that will affect your entire nation.
2. The effect of the spell is that it will prevent all vehicular accidents from ever occurring.
3. For an entire year's absence of accidents, there will be exactly one vehicular accident each year involving at most two vehicles.
4. In exchange for a "peaceful" year (motor accident-wise), the aforementioned annual accident will always result in the most morbid gruesome deaths for the people unfortunate enough to be involved in it. (Limbs thrown around, head, shoulders, knees and toes, you get the picture)

The question is, will you accept the offer? (Oh please, suspend your beliefs for the moment, the point is not the existence of actual mages or the effectiveness of spells) And as a side note, will it make any difference if your entire nation knew of your decision or not?

So far, almost everyone I knew refused the offer.

There was one inclined to accept the offer but, upon finding out that her decision will be broadcasted to the nation, she backed out and said never mind.

How about you guys? ^_^

Oh, by the way, the spell is only applicable to land vehicles.
