Boring under roads is a big market. Suppose you need to upgrade a water or sewer line but the main runs on the other side of a road. If it's a very minor road made of asphalt, cut and cover is an option. If it's a significant road paved with concrete, boring is usually the only option and it's expensive.

All kinds of services need to cross roads and the need is ubiquitous. The market is somewhat like the power wall for battery technology.
