A month ago, my department at work held a golf outing (I did not attend, but they are remarkably popular here). Over 70 people participated. Over the course of that Friday, three golf carts were rolled, one badly enough that the driver ended up with a broken arm and had to be carted to the ER.
Several engineers are now permanently banned from that course, and we may end up not having any more golf outings. So there is definitely a market for self-driving golf carts.
The downside, of course, is that they may well end up designed by the idiots who rolled them in the first place.
