One fairly obvious application of that is to have motorbikes that can act like Google self-driving car. If we replace most cars by two-wheels (say, with a roof for confort under the rain) we divide to a third the oil consumption for transport, i.e. a third of world’s oil spending. That's 20% saving on global non-renewables. “Niche”?
