Self-driving buses roll onto Helsinki's roads

The city of Helsinki, in Finland, is currently testing a pair of self-driving buses "in the wild," if you will -- that is, on active city streets. "This is actually a really big deal right now," the project's leader, Harri Santamala, told Finnish news outlet Uutiset. The tests are among the first in the world, according to Uutiset, because Finnish law doesn't mandate that a vehicle on the streets have a driver. The buses, which will be on the road till mid-September, could one day supplement existing public transit by shuttling riders to major lines. They're not exactly speed demons though.
