As a geologist, there's no scientific importance to that specific curb at all. It is a really frequent field trip stop, though. A lot of people go there when they lead field trips (I have too), and it winds up in a lot of photos. Mostly, it's a convenient photo-op in an easily accessible area. It's certainly not the only offset curb, but it arguably makes the nicest photo. There are a lot of vineyards in the area that give much more impressive examples of active tectonics, i.m.o. - It's more clear that there's a gradient of deformation. All this having been said, though, there is very frequently a lot of tension between the local department of transportation and geologists. There are a _ton_ of very significant geologic localities that have been destroyed to widen roads despite geologists begging the DOT find another way. Of course, many of these localities are roadcuts in the first place, so it's a bit hard to convince people of their significance. Also, in case anyone's wondering why the "fault" looks like the boundary between to slabs of concrete: The actual surface trace of the fault isn't exactly at the boundary of the two slabs. It's just that one slab is mostly on one side, and the other slab is mostly on the other side. The slabs are rigid, so instead of breaking, they slide past each other.
