Me too, but I've not ridden one yet. ;-)
Maybe we are more conservative than others? It's like me towing a (camping) trailer behind my bike. Touring people often get it, 'rocket riders' rarely do, but it's they who are weird as like most forms of transport, it was originally designed as just that, 'transport' and then mutated into lots of other things (like racing etc).
Plus I think they can have ABS ...
Staying upright when stopping is rarely an issue for most riders [1] (depending on the terrain and your height and strength ) but parking can be an issue, especially if on soft ground.
We turned up at one 'biker friendly' campsite in the Peak District and the owner came out with some nice wooden pads to put our side stands on when parking on the grass. ;-)

[1] We met another couple on the road beside Loch Ness who were touring Europe on their own BMW that they had flown in with them from America. She (pillion Wife) mentioned that because of the weight in their touring cases they had toppled over (onto said cases) a few times when coming to a halt. ;-)
