I have a question about the rationales of some car dashboard design. Is this on topic?
I saw that there is a tag for dashboard and for car-design, which would nicely match my question. The question is not about neither repair, nor maintenance, though (but about regulations, whihc may or may not be close enough).
The actual question is whether there are some regulations which force car manufacturers to keep roughly the same dashboard on all cars, with more or less useless indicators (for the typical driver).
For instance the temperature of the water or oil is not interesting, what is important is whether it is correct or not (or dangerously trending).
This is part of a general thought about the design of dashboards and why they are not completely configurable with today's technology.
