True but on the other hand with sensored do not expect that you can test them al with an oscilloscope.... It just takes a lot of time doing the test.

I know for every arguement you can find another one against it and that is the problem with electric drivers, too many people with an own mind wanting their own rules.

On that subject I do understand the ETS where some people make the rules and basically say "this is it, deal with it". If you want to have maximum control then yes, people do not like it but in the case of the ETS they still show up. Give them freedom on anternetives and you will end up with 30 or more different classes.
