That is a very interesting article and it says a lot about how the auto industry actually works and how decisions are made (i.e. on the basis of money - which actually makes perfect sense). On that issue, while we all whine about why Honda doesn't update the ST or why tires don't last longer - the fact is that the business case for those developments simply isn't strong enough. The vehicle industry is, afterall, a business and not a charity or public service.
The point is that our segment of the motorsport activity is really very small and that means that our "stuff" is expensive.....or that we need to find alternatives such as Darkside tires. I haven't gone that way, but I must admit that the evidence that they are safe, effective and durable is compelling.
