Turkey leads Autogas consumption in Europe, while ranks second in the world. 80% of all LPG consumed throughout the country is used as Autogas. In addition, Turkey is the only country that has more LPG vehicles more than gasoline-powered vehicles.
In Turkey, the number of LPG vehicles in operation is close to 5 million.
I don’t hate it. It’s technically interesting.
But I do see a lot of people applying it to things that really don’t need it. I think a lot of people saw Bitcoin and decided “I’m going to go make something that uses blockchains”. That’s a solution-in-search-of-a-problem, whereas you probably want to start with a problem and then look for technology that solves the problem.
I don’t think that blockchains are a very practical solution for all that many problems.
