Actually, until recently Mogas has ALWAYS had high vapor pressure.  
Nowadays it is being legislated down (by the EPA) to nearly the level of 
100LL.  I see cars along the highway too.  I'm just not prepared to make 
an unequivocal statement that the cause was carb vapors from high 
volatility Mogas.  Is it possible that instead of them all being 
25-30-year-old carburated cars, they might be poorly maintained 
10-year-old cars that ruptured a fuel line?  Are there physical failure 
modes for injectors? 
Let's not grab onto the first unsupported generality that comes our way
