DB Schenker's driverless lorry allowed on public Swedish roads

This seems pretty cool and a step in the right direction, but I do wonder what will happen if:

• The truck has some sort of accident - is there some sort of process to get physical people to the site and check out the damage etc? There's only so much one can do remotely.
• The truck looses connection - The news articles does say they have "advanced communication systems" but what happens when those communication systems go down? Will the truck keep going? Will it stop?
• Is there anything in place to remotely halt the truck in an emergency?

I suspect the lorry has tons of logistical data about how it's running and it's efficiency etc, so I'd imagine some of the above points have been addressed.

Cool, but it's (just) a cautious experiment:

The lorry is limited to 5km/h (3mph) while mixing with human-driven traffic and can make trips between only two locations, on the industrial estate.

So, allowed on one specific Swedish road, not roads, plural :-P
