Nevertheless, there's always, inevitably, an end to the road. Naturally, sometimes this is because the land just plumb runs out. But there are a number of other reasons why Google's cameras have not been able to proceed, from the natural to the man made.
Kīlauea volcano in the Kahaualea Natural Area Reserve on Hawaii's southernmost island is one of the world's most active volcanoes, boasting 61 eruptions since 1823. Its current eruption has been ongoing since 1983, and has produced 3.5 cubic kilometres of lava. We can't help but feel that a road in this area was not the best idea.

Midway Atoll, true to its name, is in a remote location in the North Pacific Ocean about midway between North America and Asia. Although it's officially a US territory, it is both unorganised and unincorporated. It's a wildlife preserve and a UNESCO World Heritage site. Quite aside from its remote location and limited outside access (permits are required), it should be quite obvious why Google Street View could not travel any farther along this jetty.
