It is because some people are praising things without first hand experience on SriLankan roads. Trying out something on your own is OK as long as you don't force or convince others with irrelevant data. When I say irrelevant data it is data shown by people about how hybrids perform on countries where infrastructure including consumer protection laws are really good and not in a country like SL.
For me hybrid is just another technology manufacturers are trying out to market their products by addressing some of the wishes of customers like fuel economy and greener transport similar to how carburetors, EFI, ABS, EBD etc was developed to address different needs of customers, they will have their own advantages/disadvantages and success/failure based on the context used.
Sad part is we are still not in a position to reject technologies that does not suite us since we are a very small market for auto makers.
