Totally different model, and my RC300h does have folding mirrors, but again not synchronised with locking. And yes, it is a pain, especially with the seating position and very wide doors.
When folded, trying to open the door without being able to see approaching traffic and cyclists is worrying, and I have to be very careful.
I share your annoyance, as l didn't check before purchase, and assumed a prestige brand would include the facility. Again, other specs of the model include it.
