Is this fair? Giving Hybrid plates to mild hybrids?

Usually, I wouldn’t care a lot, but today it was announced that Hoy No Circula will start applying to all conventional ICE vehicles. This Audi, and a few Mercs, are starting to get the Hybrid/PHEV/EV plates... despite being mild hybrids.

It also means that these cars pay no road tax, and also do not require smog checks for seven years.  OK, so it uses a lot less gas than my Kia despite being a similarly powerful car... but still. It’s not a Prius nor is it a conventional hybrid, the A7 doesn’t have an EV mode.
