Agree. I have a 981 Spyder and the blind spots with the roof raised are terrible. The key is to always drive roofless so it is never really a problemAt the same time I haven't seen anything that states it has it. It's not a government mandated feature and not all cars have it... example the 718 Spyder/GT4 does not even have it as an option. My Spyder had really bad blind spots.
Fingers crossed the Emira FE has no such **** fitted
