Well, during the 3000 km I have driven the 3W so far, I only experienced a handful (single digit) events of bump steer - but that was on really big potholes. All of these events have been mild. So, I can confidently say that bump steer has not been an issue at all for me.
I really love the feel of the steering wheel moving all the time. If Morgan offers a comfort upgrade, and even if it is for free, I will politely decline. I love the steering as it is.
That's just me, and it is on European road conditions. And maybe the 3 Wheelers do not all behave themselves the same way...

And yes, we had a GREAT day out.
