Gathering street view like data, processing it, running the service and keeping it up to date would require millions if not billions of dollars/euros in capturing equipment, server farms, wages, electricity, lawfirms.

Even if someone had the funding to get started, they would most likely get bought out by google or apple or microsoft very quickly once they got comparable results.
