Ride with others, and let someone else lead the ride who does the "stop and smell the roses" thing, and go with the flow.
That's the only thing that works for me, otherwise my endurance rider mentality kicks in hard and I just ride ride ride until I either need gas, or need a bathroom. For me, there's an appeal in this (I know not all understand it, but it's a thing for some of us), although I do recognize that sometimes I miss seeing things as a result. That being said, I'm not a big scenery gawker (I can take in scenery as I ride and enjoy it just as much really), although I am an *experience* guy - if there's something cool to stop and experience (I'll use the Diefenbunker outside Ottawa as an example) I find that very cool stuff, but if I'm solo I'd be more apt to ride past vs stopping...but I've been there twice in group rides now and really enjoyed it.
