Its ludicrous to say riding on a MUP is more perilous than riding on the road...notably because of physics, conservation of momentum. Mass and speed differential. What may be applicable and certainly not on the MUP I ride is...it 'can' be more inconveniencing to ride on a MUP because for safety based upon traffic, you can't ride wide open like you can on the road. On the MUP I ride you can ride 30 mph for mile after mile if you want. That is the distinction. But equating the safety of each is absurd. M * V = M * V If a 2 ton car contacts your 18 lb bike, bad things happen. By contrast, yes you can get hurt crashing with another bicycle on a MUP but you will likely live. Most that don't understand this either didn't take high school physics or flunked.

I have run into a truck that turned in front of me on a morning commute. So I've been there. I know the risks.
I'm not saying it's "physically" safer on streets than my particular MUP. I'm saying it's statistically safer based upon my own experiences commuting and riding compared to the local MUP, at least during peak hours.
And as far as physics goes, I do have a BS in aerospace engineering, so I have a rough handle on physics.
EDIT: And yes, statistically safer is kind of key at the moment because I'm sure it wouldn't take a whole lot to re-injure my ACL repair.
